10.1 Overview
The wild register function can be used to patch bugs in a program with
addresses and amendment data, both of which are to be set in built-in registers.
This section describes the wild register function.
■ Wild Register Function
The wild register consists of three wild register data setting registers, three wild register
address setting registers, a 1-byte address compare enable register and a 1-byte wild register
data test setting register. If addresses and data that are to be modified are set to these registers,
ROM data can be replaced with modification data set in the registers. Data of up to three
different addresses can be modified.
The wild register function can be used to debug a program after creating the mask and to patch
bugs in the program.
