10.1 Mask Option Directives
When creating the
μ
PD63 program, it is necessary to use a mask option directive in the assembler’s source
program to specify a mask option.
10.1.1 OPTION and ENDOP directives
From the OPTION directive on to the ENDOP directive are called the mask option definition block. The format
of the mask option definition block is as follows:
