GP_CONV (0x06)
The GP_CONV register selects the type of conversion to be performed when initiated by a GPIO (when the GPIO is
configured as a Conversion Start input), and selects the register to which the conversion result will be written. Writing to
this register does not execute a conversion. When a GPIO initiates a conversion, the conversion results will be written to
the data register selected by the GPIO Conversion Destination field (GP_DEST). The GPIO Conversion Type field selects
the type of conversion that will be initiated by a GPIO.

GP_SEQ_ADDR (0x07)
The GP_SEQ_ADDR register selects the target sequencer address when a sequence is initiated by a GPIO (when the
GPIO is configured as a Sequencer Start input). Writing to this register does not initiate a sequence. Valid values are
0x3A - 0x6F. Writes of invalid addresses will be ignored.
