ADuC7032-8L
High Voltage Interface Control Register
Name: HVCON
Address: 0xFFFF0804
Default Value: 0x00
Access: Read/write
Function: This 8-bit register acts as a command byte interpreter for the high voltage control interface. Bytes written to this register are
interpreted as read or write commands to a set of four indirect registers related to the high voltage circuits. The HVDAT register is used to
store data to be written to or read back from the indirect registers.

High Voltage Data Register
Name: HVDAT
Address: 0xFFFF080C
Default Value: Modified by kernel
Access: Read/write
Function: This 12-bit register is used to hold data to be written indirectly to and read indirectly from the high voltage interface registers.

Bit

Description
Reserved.
Transmit command to high voltage die status.
Read command from high voltage die status.
Busy Bit (Read Only). When user code reads this register, Bit 0 should be interpreted as the busy signal for the high voltage
interface. This bit can be used to determine if a read request has completed. High voltage (read/write) commands, as described
previously, should not be written to HVCON unless busy = 0.
Description
Command Byte 0x00 = read back High Voltage Register HVCFG0 into HVDAT.
Command Byte 0x01 = read back High Voltage Register HVCFG1 into HVDAT.
Command Byte 0x02 = read back High Voltage Status Register HVSTA into HVDAT.
Command Byte 0x03 = read back High Voltage Status Register HVMON into HVDAT.
Command Byte 0x08 = write the value in HVDAT to the High Voltage Register HVCFG0.
Command Byte 0x09 = write the value in HVDAT to the High Voltage Register HVCFG1.
All other command bytes are reserved and should not be written by user code.
Command Associated with High Voltage Data, HVDAT[7:0]. These bits are read only and should be written as 0s.
Description
High Voltage Data to Read/Write.
1 = command completed successfully.
0 = command failed.
1 = command completed successfully.
0 = command failed.
1 = high voltage interface is busy and has not completed the previous command written to HVCON; Bit 1 and Bit 2 are not valid.
0 = high voltage interface is not busy and has completed the command written to HVCON; Bit 1 and Bit 2 are valid.
0x00 = read back High Voltage Register HVCFG0 into HVDAT.
0x01 = read back High Voltage Register HVCFG1 into HVDAT.
0x02 = read back High Voltage Status Register HVSTA into HVDAT.
0x03 = read back High Voltage Status Register HVMON into HVDAT.
0x08 = write the value in HVDAT to the high voltage register HVCFG0.
0x09 = write the value in HVDAT to the high voltage register HVCFG1.
