CPU Module

Category

Compiler-Fixed

Function

PUSH #4, PUSH #8

Description

The single operand instruction PUSH cannot use the internal constants (CG) 4 and 8.  The other internal constants (0, 1, 2, -1) can be used. The number of clock cycles is different:

PUSH #CG   uses address mode 00, requiring 3 cycles, 1 word instruction
PUSH #4/#8 uses address mode 11, requiring 5 cycles, 2 word instruction

Workaround

Refer to the table below for compiler-specific fix implementation information.
