4.3. Wild Register Data Register 00 to 15 : WRDR00 to 15
(Wild Register Data Register 00 to 15)
The bit configuration of wild register data register 00 to 15 is shown.
These registers set the replacement data. When the contents of the memory at the addresses specified by the
wild register address registers (WRAR00 to WRAR15) are read, the value set in these registers is returned
instead of the actual contents of the memory.
The read value of these registers is undefined while the wild register function is operating.
Always set these registers in units of 32 bits.
