1.2 Introduction
The MC68HC05RC17 is a general-purpose, low-cost addition to the
M68HC05 Family of microcontroller units (MCUs) and is suitable for
remote control applications. It contains the HC05 central processing unit
(CPU) core, including the 14-stage core timer with real-time interrupt
(RTI) and computer operating properly (COP) watchdog systems. On-
chip peripherals include a carrier modulator transmitter. The 16-Kbyte
memory map has 15,936 bytes of user ROM and 352 bytes of RAM.
There are 18 input-output (I/O) lines (eight having keyscan logic and
pullups) and a low-power reset pin.
