Caution: Exceeding the absolute maximum ratings shown in table 23.1 can permanently destroy the chip.*

Note: * FVPP must not exceed 13 V and VPP must not exceed 13.5 V, including allowances for peak overshoot. For the dual-power-supply F-ZTAT version, MD1 must not exceed 13 V, including an allowance for peak overshoot.




Description

All the H8/3437 Series general registers can be used as both data registers and address registers. When used as address registers, the general registers are accessed as 16-bit registers (R0 to R7). When used as data registers,H8/3437 Series can be accessed as 16-bit registers, or the high and low bytes can be accessed separately as 8-bit registers (R0H to R7H and R0L to R7L). R7 also functions as the stack pointer, used implicitly by hardware in processing interrupts and subroutine calls. In assembly-language coding, R7 can also be denoted by the letters SP. As indicated in figure 2.2, R7 (SP) points to the top of the stack.
