Stack
A stack is a register to save a program return address and the contents of system registers (to be described later) when
a subroutine is called or when an interrupt is accepted.
2.3.1
Stack configuration
Figure 2-3 shows the stack configurarion.
A stack consists of a stack pointer (a 4-bit binary counter, the high-order 1 bit fixed to 0), five 11-bit (

PD17225)/12-
bit (
μ
PD17226)/13-bit (
μ
PD17227, 17228) address stack registers, and three 5-bit (
μ
PD17225, 17226)/6-bit (
μ
PD17227,
17228) interrupt stack registers.
