3.3.5 Program Counter (PC)
The program counter is a 13-bit register that contains the address of the
next byte to be fetched.
NOTE:
The HC05 CPU core is capable of addressing 16-bit locations. For this
implementation, however, the addressing registers are limited to an 8K
byte memory map.
3.4 Instruction Set
The MCU has a set of 62 basic instructions. They can be divided into five
different types: register/memory, read-modify-write, branch, bit
manipulation, and control. The following paragraphs briefly explain each
type. For more information on the instruction set, refer to the
M6805
Family User’s Manual (M6805UM/AD2) or the MC68HC05C4 Data
Sheet (MC68HC05C4/D).
