ADuC7032-8L
High Voltage Monitor Register
Name: HVMON
Address: Indirectly addressed via the HVCON high voltage interface
Default Value: 0x00
Access: Read only
Function: This 8-bit, read-only register reflects the current status of enabled high voltage related circuits and functions on the ADuC7032-8L.
This register is not an MMR and does not appear in the MMR memory map. It is accessed via the HVCON registered interface, and data
is read back from this register via HVDAT.

Description
Overtemperature.
Reserved. This bit should not be used and is reserved for future use.
Buffer Enabled.
Low Voltage Flag Status Bit. (Valid only if enabled via HVCFG0[2].)
LIN Short-Circuit Status Flag.
Reserved. This bit should not be used and is reserved for future use.
WU Short-Circuit Status Flag.
WU Pin Diagnostic Readback. Once enabled via HVCFG1[4], this read-only bit reflects the state of the external WU (wake-up) pin.
This bit is 0 if a thermal shutdown event has not occurred.
This bit is 1 if a thermal shutdown event has occurred.
This bit is 0 if the voltage channel ADC input buffer is disabled.
This bit is 1 if the voltage channel ADC input buffer is enabled.
This bit is 0 on power-up if REG_DVDD has dropped below 2.1 V. In this state, RAM contents can be deemed corrupt.
This bit is 1 on power-up if REG_DVDD has not dropped below 2.1 V. In this state, RAM contents can be deemed valid.
This bit is 0 if the LIN driver is operating normally.
This bit is 1 if the LIN driver has experienced a short-circuit condition and is cleared automatically by writing to HVCFG1[3].
This bit is 0 if the WU driver is operating normally.
This bit is 1 if the WU driver has experienced a short-circuit condition.
It is cleared only by re-enabling the low voltage flag in HVCFG0[2].
