- Page 12 GMS90C320 Function Description The GMS90 series is fully compatible to the standard 8051 microcontroller family. It is compatible with the standard 80C32. While maintaining all architectural and operational characteristics of the standard 80C32, the GMS90C320 incorporates some enhancements in the Timer 2 unit. Figure 1 shows a block diagram of the GMS90C320 XTAL1 256 x 8...
- Page 13 GMS90C320 The GMS90C320 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 con- sisting of 44% one-byte, 41% two-byte, and 15% three-byte instructions.
- Page 14 GMS90C320 Special Function Registers All registers, except the program counter and the four general purpose register banks, reside in the special function register area. The 27 special function registers (SFR) include pointers and registers that provide an interface between the CPU and the other on-chip peripherals.

- Page 24 GMS90C320 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.
