Page 12 GMS90 Series PIN DEFINITIONS AND FUNCTIONS Pin Number Input/ Symbol Function Output PLCC- PDIP- MQFP- P1.0-P1.7 40-44, Port1 Port 1 is an 8-bit bidirectional I/O port with internal pull-ups. Port 1 pins that have 1s written to them are pulled high by the internal pull-up resistors and can be used as inputs.
Page 13 GMS90 Series Pin Number Input/ Symbol Function Output PLCC- PDIP- MQFP- XTAL1 XTAL1 Input to the inverting oscillator amplifier and input to the internal clock generator circuits.To drive the device from an external clock source, XTAL1 should be driven, while XTAL2 is left unconnected. There are no requirements on the duty cycle of the external clock signal, since the input to the internal clocking circuitry is divided down by a divide-by-two flip-flop.
Page 14 GMS90 Series Pin Number Input/ Symbol Function Output PLCC- PDIP- MQFP- ALE / The Address Latch Enable / Program pulse PROG Output pulse for latching the low byte of the address during an access to external memory. In normal operation, ALE is emitted at a constant rate of 1/6 the oscillator frequency, and can be used for external timing or clocking.
Page 15 GMS90 Series FUNCTIONAL DESCRIPTION The GMS90 series is fully compatible to the standard 8051 microcontroller family. It is compatible with the general 8051 family.

Page 16 GMS90 Series The GMS90 series is efficient both as a controller and as an arithmetic processor. It has extensive facilities for binary and BCD arithmetic and excels in its bit-handling capabilities. Efficient use of program memory results from an instruction set consisting of 44% one-byte, 41% two-byte, and 15% three-byte instructions. With a 12 MHz crystal, 58% of the instructions are executed in 1.0µs (40MHz: 300ns).
Page 17 GMS90 Series SPECIAL FUNCTION REGISTERS All registers, except the program counter and the four general purpose register banks, reside in the special func- tion register area. The 28 special function registers (SFR) include pointers and registers that provide an interface between the CPU and the other on-chip peripherals.

Page 24 GMS90 Series TIMER 2 Timer 2 is a 16-bit timer/Counter with an up/down count feature. It can operate either as timer or as an event counter which is selected by bit C/T2 (T2CON.1). It has three operating modes as shown in Table 5. Table 5.
Page 25 GMS90 Series SERIAL INTERFACE (USART) The serial port is full duplex and can operate in four modes (one synchronous mode, three asynchronous modes) as illustrated in Table 6. The possible baud rates can be calculated using the formulas given in Table 7. Table 6.
Page 26 GMS90 Series INTERRUPT SYSTEM The GMS90 series provides 5 (4K bytes ROM version) or 6 (above 8K bytes ROM version) interrupt sources with two priority levels. Figure 3 gives a general overview of the interrupt sources and illustrates the request and control flags.

Page 28 GMS90 Series Power Saving Modes Two power down modes are available, the Idle Mode and Power Down Mode. The bits PDE and IDLE of the register PCON select the Power Down mode or the Idle mode, respectively. If the Power Down mode and the Idle mode are set at the same time, the Power Down mode takes precedence. Table 10 gives a general overview of the power saving modes.

Page 51 GMS90 Series EPROM CHARACTERISTICS The GMS97C5X, 97L5X are programmed by using a modified Quick-Pulse Programming algorithm. It dif- fers from older methods in the value used for V (programming supply voltage) and in the width and number of the ALE/PROG pulses. The GMS97C5X, 97L5X contains two signature bytes that can be read and used by an EPROM programming system to identify the device.
Page 52 GMS90 Series encryption table is disabled. However, the other security bit can still be programmed. Note that the EA/V must not be allowed to go above the maximum specified V level for any amount of time. Even a narrow glitch above that voltage can cause permanent damage to the device.
