CRCERI 0
R/W CRC Error Interrupt Flag
ERR
0: No interrupt
[Clearing condition]
Write 0 after reading CRCERI = 1.
(Writing 1 is invalid)
1: Interrupt requested
[Setting condition]
When a CRC error for command response
or receive data or a CRC status error for
transmit data response is detected while
CRCERIE = 1.
For the command response, CRC is
checked when the RTY4 in RSPTYR is
enabled.

DTERI
0
R/W Data Timeout Error Interrupt Flag
0: No interrupt
[Clearing condition]
Write 0 after reading DTERI = 1.
ERR
(Writing 1 is invalid)
1: Interrupt requested
[Setting condition]
When a data timeout error specified in
DTOUTR occurs while DTERIE = 1.
