Initial value: 00H
NOTE)
1. Used only to Auto CRC Mode.
FCCR (Flash CRC Control Register): 5056H
Initial value: 00H
Flash CRC Data Register Clear
Clear Flash CRC Data register
NOTE)
1. This bit is set to ‘0’ automatically, after Flash CRC Data register is
cleared. FCDRH/L is cleared to “FFH”. Used only to User CRC Mode.
f
X
(main system clock frequency)
CRC/Checksum Start Signal & Busy Flag, Used only to Auto CRC/Checksum mode.
Indicates that CRC/Checksum operation is not running or has finished.
When written “0”, CRC/Checksum operation is finished by force even if
CRC/Checksum operation is running. It has no effect to write “0” if
CRC/Checksum is not running currently.
When written “1”, CRC/Checksum operation starts and this bit remains “1” as
long as CRC/Checksum operation is on-going. This bit is cleared to “0”
automatically after CRC/Checksum operation finishes.
NOTE)
1. If fHFIRC, fHFIRC/2, fHFIRC/4 and fHFIRC/8 is selected, HFIRCE must be cleared to ‘0’ at OSCCR.
