4.3.2
Function of Stack
The address stack register stores a return address when the subroutine call instruction or table reference instruction
(first instruction cycle) is executed or when an interrupt is accepted. It also stores the contents of the address registers
(ARs) when a stack manipulation instruction (PUSH AR) is executed.
The WDOUT pin goes low if a subroutine call or interrupt exceeding 5 levels is executed.
The interrupt stack register (INTSK) saves the contents of the bank register (BANK) and program status word
(PSWORD) when an interrupt is accepted. The saved contents are restored when an interrupt return (RETI) instruction
is executed.
INTSK saves data each time an interrupt is accepted, but
the data stored first is lost if more than 3 levels of
interrupts occur
.
4.3.3
Stack Pointer (SP) and Interrupt Stack Pointer
Table 4-1 shows the operations of the stack pointer (SP).
The stack pointer can take eight values, 0H-07. Because there are only five stack registers available, however,
the WDOUT pin goes low if the value of SP is 6 or greater
