Reserved
These bits are always read as 0 and cannot be
modified.
CRC Error Interrupt Flag
0: No interrupts
1: MCIFI2 interrupt requested.
[Setting condition]
•
When a CRC error for command response or
receive data, and status error (CRC error) for
transmission data response is detected while
CRCERIE = 1 in INTCR1.
For the command response, CRC should be
checked when the RTY4 bit in RSPTYR is
enabled.
[Clearing condition]
•
Write 0 after reading CRCERI = 1.
Data Timeout Error Interrupt Flag
0: No interrupts
1: MCIFI2 interrupt requested.
[Setting condition]
•
When a data timeout error specified in
DTOUTR occurs while DTERIE = 1 in
INTCR1.
[Clearing condition]
•
Write 0 after reading DTERI = 1.
Command Timeout Error Interrupt Flag
0: No interrupts
1: MCIFI2 interrupt requested.
[Setting condition]
•
When a command timeout error specified in
CTOCR occurs while CTERIE = 1 in INTCR1.
[Clearing condition]
•
Write 0 after reading CTERI = 1.
