7.2.2 Internal peripherals
8. MASK OPTION
section explains these mask options. The mask options are specified in the Workbench (WB77016) development
tool. To order a mask ROM, output a mask ROM ordering file format (.msk file) using WB77016.

X/Y Memory Address
The internal peripherals are mapped to the internal data memory space.
Cautions 1. The register names listed in this table are not reserved words of the assembler or the C
The PD77111 and 77112 have mask options that must be specified when an order for a ROM is placed. This
The following four clock related options must be specified.
• PLL multiple
• Output division ratio
• HALT division ratio
• Validity of CLKOUT pin
