Sep 30, 2010
(1) CRC input register (CRCIN)
(2) CRC data register (CRCD)
The CRCIN register is an 8-bit register for setting data.
This register can be read or written in 8-bit units.
Reset sets this register to 00H.
The CRCD register is a 16-bit register that stores the CRC-CCITT operation results.
This register can be read or written in 16-bit units.
Reset sets this register to 0000H.
Caution Accessing the CRCD register is prohibited in the following statuses. For details, refer to 3.4.9 (2)
