Table Data Processing Instructions
Section 3-17
Description
PUSH(632) writes the content of S to the address indicated by the stack
pointer (TB+3 and TB+2) and increments the stack pointer by one.
After PUSH(632) has been used to write data into a stack, FIFO(633) and
LIFO(634) can be used to read data from the stack.
Flags
Precautions
The stack must be defined in advance with SSET(630).
