Section 2 CPU
General register ER7 has the function of stack pointer (SP) in addition to its general-register
function, and is used implicitly in exception handling and subroutine branches. Figure 2.11 shows
the stack.
2.5.2
PC is a 32-bit counter that indicates the address of the next instruction the CPU will execute. The
length of all CPU instructions is 16 bits (one word) or a multiple of 16 bits, so the least significant
bit is ignored. (When the instruction code is fetched, the least significant bit is regarded as 0.
