1.2 Introduction
The MC68HC705P6A is an EPROM version of the MC68HC05P6
microcontroller. It is a low-cost combination of an M68HC05 Family
microprocessor with a 4-channel, 8-bit analog-to-digital (A/D) converter,
a 16-bit timer with output compare and input capture, a serial
communications port (SIOP), and a computer operating properly (COP)
watchdog timer. The M68HC05 CPU core contains 176 bytes of RAM,
4672 bytes of user EPROM, 239 bytes of bootloader ROM, and 21
input/output (I/O) pins (20 bidirectional, 1 input-only). This device is
