Read/write
This 8-bit register controls the function of high voltage circuits on the ADuC7033. This register is not an MMR and
does not appear in the MMR memory map. It is accessed via the HVCON registered interface. Data to be written to
this register is loaded via the HVDAT MMR, and data is read back from this register via the HVDAT MMR.
Description
Wake/STI Thermal Shutdown Disable.
Precision Oscillator Enable Bit.
Bit Serial Device (BSD) Mode Enable Bit.
Wake Up (WU) Assert Bit.
Power Supply Monitor (PSM) Enable Bit.
Low Voltage Flag (LVF) Enable Bit.
LIN Operating Mode. These bits enable/disable the LIN driver.
Set to 1 to disable the automatic shutdown of the wake/STI driver when a thermal event occurs.
Cleared to 0 to enable the automatic shutdown of the wake/STI driver when a thermal event occurs.
Set to 1 to enable the precision, 131 kHz oscillator. The oscillator start-up time is typically 70 μs (including high
voltage interface latency of 10 μs).
Cleared to 0 to power down the precision, 131 kHz oscillator.
Cleared to 0 to enable an internal (LIN) pull-up resistor on the LIN/BSD pin.
Set to 1 to disable the internal (LIN) pull-up and configure the LIN/BSD pin for BSD operation.
Set to 1 to assert the external WU pin high.
Cleared to 0 to pull the external WU pin low via an internal 10 kΩ pull-down resistor.
Cleared to 0 to disable the power supply (voltage at the VDD pin) monitor.
Set to 1 to enable the power supply (voltage at the VDD pin) monitor. If the voltage at the VDD pin drops below
6.0 V while IRQ3 (IRQEN[16]) is enabled, the PSM generates an interrupt.
Cleared to 0 to disable the LVF function.
Set to 1 to enable the LVF function. The low voltage flag can be interrogated via HVMON[3] after power up to
determine if the REG_DVDD voltage previously dropped below 2.1 V.
00 = LIN disabled.
01 = reserved (not LIN 2.0 compliant).
10 = LIN enabled.
11 = reserved, not used.
