OVTCiF: TC Overflow error interrupt Flag Bit
Indicates the time base counter overflow error interrupt cause occurrence status.
1 (R):
Cause of interrupt has occurred
0 (R):
No cause of interrupt has occurred (default)
1 (W):
Flag is reset
0 (W):
Ignored
OVTCIF is set to 1 when a reference oscillation is terminated abnormally due to time base counter
overflow. OVTCIF is reset to 0 by writing 1.
D3
OVMCiF: MC Overflow error interrupt Flag Bit
Indicates the measurement counter overflow error interrupt cause occurrence status.
1 (R):
Cause of interrupt has occurred
0 (R):
No cause of interrupt has occurred (default)
1 (W):
Flag is reset
0 (W):
Ignored
OVMCIF is set to 1 when a sensor oscillation is terminated abnormally due to measurement counter
overflow. OVMCIF is reset to 0 by writing 1.
D2
eSenBiF: Sensor B Oscillation Completion interrupt Flag Bit
Indicates the sensor B oscillation completion interrupt cause occurrence status.
1 (R):
Cause of interrupt has occurred
0 (R):
No cause of interrupt has occurred (default)
1 (W):
Flag is reset
0 (W):
Ignored
ESENBIF is set to 1 when the time base counter reaches 0x0 and a sensor B oscillation is completed
normally. ESENBIF is reset to 0 by writing 1.
D1
eSenaiF: Sensor a Oscillation Completion interrupt Flag Bit
Indicates the sensor A oscillation completion interrupt cause occurrence status.
1 (R):
Cause of interrupt has occurred
0 (R):
No cause of interrupt has occurred (default)
1 (W):
Flag is reset
0 (W):
Ignored
ESENAIF is set to 1 when the time base counter reaches 0x0 and a sensor A oscillation is completed
normally. ESENAIF is reset to 0 by writing 1.
D0
eReFiF: Reference Oscillation Completion interrupt Flag Bit
Indicates the reference oscillation completion interrupt cause occurrence status.
1 (R):
Cause of interrupt has occurred
0 (R):
No cause of interrupt has occurred (default)
1 (W):
Flag is reset
0 (W):
Ignored
EREFIF is set to 1 when the measurement counter overflows and a reference oscillation is completed
normally. EREFIF is reset to 0 by writing 1.
