    There are four Nonvolatile Registers named OR0, OR1, OR2, and OR3 individually. They are designed to configure the MPC82x54A, i.e.,: to decide to use internal RC oscillator or use crystal oscillator as oscillating source, or to allocate the built-in flash for application program, application data and In-System-Program code.

  • Page 20: Functional Description

    Functional Description I/O Port Configuration All 27 port pins on MPC82x54A may be independently configured to one of four modes: quasi-bidirectional (standard 8051 port output), push-pull output, open-drain output or input-only. All port pins default to quasi-bidirectional after reset. Each port pin has a Schmitt-triggered input for improved input noise rejection.

  • Page 24: Timer/Counter

    Timer/Counter MPC82x54A has two 16-bit timers, and they are named T0 and T1. Each of them can also be used as a general event counter, which counts the transition from 1 to 0. Since the MPC82x54A is a RISC-like MCU which executes faster than traditional 80C51 MCU from other providers.

  • Page 29: Interrupt

    Interrupt There are seven interrupt sources available in MPC82x54A. Each interrupt source can be individually enabled or disabled by setting or clearing a bit in the SFR named IE. This register also contains a global disable bit (EA), which can be cleared to disable all interrupts at once.

  • Page 33: Watch Dog Timer

    Watch Dog Timer The watch dog timer in MPC82x54A consists of an 8-bit pre-scalar timer and a 15-bit timer. The timer is one-time enabled by setting ENW. Clearing ENW can not stop WDT counting. When the WDT is enabled, software should always reset the timer by writing 1 to CLRW bit before the WDT overflows.

  • Page 35: Universal Asynchronous Serial Port (Uart)

    Universal Asynchronous Serial Port (UART) The serial port of MPC82x54A is duplex. It can transmit and receive simultaneously. The receiving and transmitting of the serial port share the same SFR SBUF, but actually there are two SBUF registers implemented in the chip. One is for transmitting and the other is for receiving.
  • Page 36 RB8:= In mode 2 and 3, the received 9th data bit will be put into this bit. TI:= Transmitting done flag. After a transmitting has been finished, the hardware will set this bit. RI:= Receive done flag. After reception has been finished, the hardware will set this bit. MPC82x54A Data Sheet MEGAWIN...
  • Page 37 Normally, an UART will set bit RI whenever it has done a byte reception; but, for the UART in the MPC82x54A, if the bit SM2 is set, it will set RI according to the following formula. RI = (SM2 == 1) && (SBUF == Compared Byte) && (RB8 == 1) In other words, not all data reception will respond to RI while specific data does.

    The CCON SFR contains the run control bit for PCA and several flags for the PCA timer and each module.
