10.1 Mask Option Directives
When creating the µPD62A 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
The assembler directives from the OPTION directive to the ENDOP directive are called the mask option definition
block. The format of the mask option definition block is as follows:
