Read only
This 8-bit, read only register reflects the status of the enabled high voltage features. This register is not an MMR and
does not appear in the Complete MMR Listing section. It is indirectly accessed via the HVCON MMR, and data is read
back from this register via the HVDAT MMR.
Description
WU pin diagnostic readback. When enabled via HVCFG1[4], this read only bit reflects the state of the external WU pin.
Overtemperature.
0 = a thermal shutdown event has not occurred.
1 = a thermal shutdown event has occurred.
STI pin diagnostic readback. When enabled via HVCFG1[4], this read only bit reflects the state of the external STI pin.
Buffer enabled.
0 = the voltage channel ADC input buffer is disabled.
1 = the voltage channel ADC input buffer is enabled.
Low voltage flag status bit. Only valid if enabled via HVCFG0[2].
0 (on power-on) = REG_DVDD has dropped below 2.1 V. In this state, RAM contents can be deemed corrupt.
1 (on power-on) = REG_DVDD has not dropped below 2.1 V. In this state, RAM contents can be deemed valid. It is only
cleared by re-enabling the low voltage flag in HVCFG0[2].
LIN/BSD short-circuit status flag.
0 = the LIN/BSD driver is operating normally.
1 = the LIN/BSD driver has experienced a short-circuit condition and is cleared automatically by writing to HVCFG1[3].
STI short-circuit status flag.
0 = the STI driver is operating normally.
1 = the STI driver has experienced a short-circuit condition, and it is cleared automatically by writing to HVCFG1[3].
Wake-up short-circuit status flag.
0 = the wake-up driver is operating normally.
1 = the wake-up driver has experienced a short-circuit condition.
