Description
CIR Busy Flag
Indicates the data receive state of the CIR.
[Setting condition]
When the CIR starts data reception.
[Clearing condition]
When the CIR has finished data reception.
Receive Data Register Full
Indicates whether CIRRDR contains a receive data
or not. This bit cannot be modified.
[Setting condition]
When a receive data is stored into CIRRDR.
[Clearing condition]
When a receive data has been read from CIRRDR.
Repeat Detection Flag
Indicates a repeat is generated.
[Setting condition]
When a repeat is detected.
[Clearing condition]
When writing 0 after reading REPF = 1.
Overrun Error Flag
Indicates CIRRDR overflows.
[Setting condition]
When the next data is stored in CIRRDR while
CIRRDR is full.
[Clearing condition]
When writing 0 after reading OVRF = 1.
