ADC Status Register (ADCSTS)

This register indicates the global status of the ADC module. ADCSTS is cleared (0016)onVCC Power-Up reset; on other

resets, bit 2 is unchanged and other bits are cleared.

Description

0RO

EOCEV (End-of-Cycle Event). End of ADC cycle; all enabled measurements (up to four) are

completed. For each of the enabled channels, the DATVAL bit in the respective TCHANCTL VCHNxCTL

0: Cycle in progress (default)

1: End of ADC cycle (the bit remains set until all DATVAL bits in the Channel Control registers are reset)

R/W1C OVFEV (Data Overﬂow Event). Measurement data from the previous cycle was overwritten with data

from the current cycle before being read. In the event of a data overﬂow, the DATVAL bit remains set

and new data is placed in Channel Data Buffer register.

0: No overflow (default)

1: Overflow

R/W1C OTSEV (Overtemperature Signal Event). Temperature measured by local diode exceeded the limit.

0: Temperature below or equal to the limit (VCC Power-up reset default)

1: Temperature above limit (once set, this bit is cleared by writing 1 to it; writing 0 is ignored)

R/W1C OPSHEV (Open/Short Event). Remote diode connection failure (cable shorted or disconnected).

Checked before the beginning of the remote diode temperature measurement (if enabled, REMDEN in

ADCCNF register and RDMEASEN in TCHANCTL register are set to 1).

0: No fault was detected (default)

1: Connection failure - the cable was shorted or disconnected (once set, this bit is cleared by writing 1 to

it; writing 0 is ignored)

4RO

OPSHTYPE (Open or Short Type). Remote diode connection failure type. Indicates the type of error

ﬂagged by OPSHEV.

0: DP shorted to DN or to AGND (default)

1: DP disconnected (floating) or shorted to AVCC
