STACK OPERATIONS

OVERVIEW

The stack buffer of SN8P1700 has 8-level high area and each level is 12-bits length. This buffer is designed to save
and restore program counter’s (PC) data when interrupt service is executed. The STKP register is a pointer designed
to point active level in order to save or restore data from stack buffer for kernel circuit. The STKnH and STKnL are the
12-bit stack buffers to store program counter (PC) data.
