27.3 Registers
888
(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. If a wait cycle is
CRCIN
CRCD
After reset: 0000H
After reset: 00H
generated, it can only be cleared by a reset. For details, see 3.4.9 (1) Accessing specific on-
chip peripheral I/O registers.
• When the CPU operates on the subclock and main clock oscillation is stopped
• When the CPU operates on the internal oscillator clock
