GNU Info (as.info)H8/300-RegsRegister Names .............. You can use predefined symbols of the form `rNh' and `rNl' to refer to the H8/300 registers as sixteen 8-bit general-purpose registers. N is a digit from `0' to `7'); for instance, both `r0h' and `r7l' are valid register names. You can also use the eight predefined symbols `rN' to refer to the H8/300 registers as 16-bit registers (you must use this form for addressing). On the H8/300H, you can also use the eight predefined symbols `erN' (`er0' ... `er7') to refer to the 32-bit general purpose registers. The two control registers are called `pc' (program counter; a 16-bit register, except on the H8/300H where it is 24 bits) and `ccr' (condition code register; an 8-bit register). `r7' is used as the stack pointer, and can also be called `sp'. automatically generated by info2www version 1.2.2.9 |
