GENERAL DESCRIPTION
The MC68HC05P9A is a 28-pin device based on the MC68HC05P9. The memory
map includes 2112 bytes of user ROM and 128 bytes of RAM. The MCU has two
8-bit input/output (I/O) ports, A and C. Port B has three I/O pins and port D has
two pins, one that is I/O and the other input only. The MC68HC05P9A includes a
four-channel 8-bit analog-to-digital (A/D) converter, a simple serial I/O peripheral
(SIOP), and an on-chip mask programmable computer operating properly (COP)
watchdog circuit.
