      Philips Semiconductors
      Preliminary specification
      P87C51MB2/P87C51MC2
      80C51 8-bit microcontroller family with extended memory
      64KB/96KB OTP with 2KB/3KB RAM
      DATA RAM
      The P87C51MB2 and P87C51MC2 have 2 Kbytes and 3 K bytes of on-chip RAM respectively. Usages of the different data 
      segments are described in the 51MX Architecture Reference.
      PORT 4
      The P87C51Mx2 has a fifth I/O port (Port 4) that is shared with the second UART pins (RXD1 and TXD1) and two of the SPI pins 
      (MISO and SS). This port is also bit addressable and can be accessed in the same manner as any other ports, except that the 
      associated SFR is in the extended SFR space. Accesses to this SFR space is the same as those to the conventional SFR space 
      except that the instructions must be preceeded by an escape code (A5h), as described in the 51MX Architecture Reference.
      LOW POWER MODES
      The P87C51Mx2 supports the standard 51MX low power modes - Stop Clock Mode, Idle Mode and Power-Down Mode.
      The PCON register is the same as the standard 51MX PCON register. Note that bits PCON.7 and PCON.6 are for UART 
      configurations (see section "UARTs").
      ONCE
      MODE
      The ONCE (“On-Circuit Emulation”) Mode facilitates testing and debugging of systems without the device having to be removed 
      from the circuit. It is supported in the P87C51Mx2.
      PERIPHERALS
      The P87C51Mx2 peripherals are described in more detail in the User Manual. The on-chip peripherals include:
       Timers:
      - Timers 0  and 1.
      - Timer 2.
      Note: 
      When Timer 1 or Timer 2 can only be used as a baud rate generator for UART 0, but not for UART 1.
       Two enhanced UARTs with an independent Baud Rate Generator - The section "UARTs" provides information regarding the 
      two UARTs.
      Note: 
      UART 1 shares the RXD1 and TXD1 with the SPI pins. The SPEN (SPCTL.6) bit must be cleared ’0’ (reset value) to 
      enable UART 1 operation.
       Serial Peripheral Interface (SPI). 
      Note: 
      The SPI shares pins with the UART 1 shares the RXD1 and TXD1 with the SPI pins. 
      The SPEN (SPCTL.6) bit must be set to ’1’ to enable SPI operation.
       Watchdog Timer.
       Programmable Counter Array (PCA).
