8.9.2.2 Register Names

You can use the predefined symbols `r0', `r1', `r2', `r3', `r4', `r5', `r6', and `r7' to refer to the H8/500 registers.

The H8/500 also has these control registers:

cp

code pointer

dp

data pointer

bp

base pointer

tp

stack top pointer

ep

extra pointer

sr

status register

ccr

condition code register

All registers are 16 bits long. To represent 32 bit numbers, use two adjacent registers; for distant memory addresses, use one of the segment pointers (cp for the program counter; dp for r0-r3; ep for r4 and r5; and tp for r6 and r7.
