RX23W Group 39. CRC Calculator (CRC)
39.2.3 CRC Data Output Register (CRCDOR)
CRCDOR is a readable and writable register.
Since its initial value is 0000h, rewrite the CRCDOR register to perform calculation using a value other than the initial
value.
Data written to the CRCDIR register is CRC calculated and the result is stored in the CRCDOR register. If the CRC code
is calculated following the transferred data and the result is 0000h, there is no CRC error.
When an 8-bit CRC (X
8
+ X
2
+ X + 1 polynomial) is in use, the valid CRC code is obtained in the low-order byte (b7 to
b0). The high-order byte (b15 to b8) is not updated.
Address(es): 0008 8282h
b15 b14 b13 b12 b11 b10 b9 b8 b7 b6 b5 b4 b3 b2 b1 b0
