CHAPTER 10 WILD REGISTER FUNCTION
10.2 Configuration
● Memory area block
The memory area block consists of the wild register data setting registers (WRDR), wild
register address setting registers (WRAR), wild register address compare enable register
(WREN) and wild register data test setting register (WROR). The wild register function is used
to specify the addresses and data that need to be replaced. The wild register address compare
enable register (WREN) enables the wild register function for each wild register data setting
register (WRDR). In addition, the wild register data test setting register (WROR) enables the
normal read function for each wild register data setting register (WRDR).
● Control circuit block
This circuit compares the actual address data with addresses set in the wild register address
setting registers (WRAR). If they match, the circuit outputs the data from the wild register data
setting register (WRDR) to the data bus. The operation of the control circuit block is controlled
by the wild register address compare enable register (WREN).
