CHAPTER 15 WILD REGISTER
Memory area block
The memory area block consists of the wild register data setup registers (WRDR), wild register address
setup registers (WRAR), wild register address compare enable register (WREN) and wild register data test
setup 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 setup register (WRDR). Moreover, the wild register data test setup register (WROR)
enables the normal read function for each wild register data setup register (WRDR).
Control circuit block
This circuit compares the actual address data with addresses set in the wild register address setup registers
(WRDR), and if the values match, outputs the data from the wild register data setup register (WRDR) to the
data bus. The control circuit block uses the wild register address compare enable register (WREN) to
control the operation.
