Bit 0 (Read Only) BUSY Bit
When user code reads this register, Bit0 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 above should not be
written to HVCON unless BUSY=0.
BUSY = 1, High voltage interface is busy and has not completed the previous command written to HVCON. Bit 1 and bit 2 are
not valid.
BUSY = 0, High voltage interface is not busy and has completed the command written to HVCON. Bit 1 and bit 2 are valid.

Read/Write
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 4 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

Interpreted as
Read back high voltage register HVCFG0 into HVDAT
Read back high voltage register HVCFG1 into HVDAT
Read back high voltage status register HVSTA into HVDAT
Read back high voltage status register HVMON into HVDAT
Write the value in HVDAT to the high voltage register HVCFG0
Write the value in HVDAT to the high voltage register HVCFG1
