45.7.13 AFEC Interrupt Status Register
Name: AFEC_ISR
Address: 0x400B0030 (0), 0x400B4030 (1)
Access: Read-only
 EOCx: End of Conversion x
0: The corresponding analog channel is disabled, or the conversion is not finished. This flag is cleared when reading the
AFEC_CDR if the CSEL field is programmed with ‘x’ in the AFEC_CSELR.
1: The corresponding analog channel is enabled and conversion is complete.
 TEMPCHG: Temperature Change
0: There is no comparison match (defined in the AFEC_TEMPCMPR) since the last read of AFEC_ISR
1: The temperature value reported on AFEC_CDR (AFEC_CSELR.CSEL=15) has changed since the last read of
AFEC_ISR according to what is defined in the temperature mode register (AFEC_TEMPMR) and the temperature compare
window register (AFEC_TEMPCWR).
 DRDY: Data Ready
0: No data has been converted since the last read of AFEC_LCDR.
1: At least one data has been converted and is available in AFEC_LCDR.
 GOVRE: General Overrun Error
0: No General Overrun Error occurred since the last read of AFEC_ISR.
1: At least one General Overrun Error has occurred since the last read of AFEC_ISR.
 COMPE: Comparison Error
0: No Comparison Error since the last read of AFEC_ISR.
1: At least one Comparison Error has occurred since the last read of AFEC_ISR.
 ENDRX: End of RX Buffer
0: The Receive Counter Register has not reached 0 since the last write in AFEC_RCR or AFEC_RNCR.
1: The Receive Counter Register has reached 0 since the last write in AFEC_RCR or AFEC_RNCR.
 RXBUFF: RX Buffer Full
0: AFEC_RCR or AFEC_RNCR have a value other than 0.
1: Both AFEC_RCR and AFEC_RNCR have a value of 0.
