HIGH VOLTAGE PERIPHERAL CONTROL INTERFACE REGISTERS
High Voltage Interface Control Register
Name:
HVCON
Address:
0xFFFF0804
Default Value:
Updated by kernel
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.
Table 70. HVCON MMR Write Bit Designations
Bit
Description
7 to 0
Command byte. Interpreted as
0x00 = read back the HVCFG0 high voltage register into HVDAT.
0x01 = read back the HVCFG1 high voltage register into HVDAT.
0x02 = read back the HVSTA high voltage status register into HVDAT.
0x03 = read back the HVMON high voltage status register into HVDAT.
0x08 = write the value in HVDAT to the HVCFG0 high voltage register.
0x09 = write the value in HVDAT to the HVCFG1 high voltage register.
Table 71. HVCON MMR Read Bit Designations
Bit
Description
7 to 3
Reserved.
2
Transmit command to high voltage die status.
1 = command completed successfully.
0 = command failed.
1
Read command from high voltage die status.
1 = command completed successfully.
0 = command failed.
0
Bit 0 (read only) busy bit. 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 in this table, should not be written to HVCON unless busy = 0.
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.
