Description
Reserved
These bits are always read as 0. The write
value should always be 0.
CRC Error Interrupt Flag
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.
Data Timeout Error Interrupt Flag
0: No interrupt
[Clearing condition]
Write 0 after reading DTERI = 1.
(Writing 1 is invalid)
1: Interrupt requested
[Setting condition]
When a data timeout error specified in
DTOUTR occurs while DTERIE = 1.
