GPO Configuration
To GPO configure a row or column, do the following:
1. Clear the bit for the row or column that needs to be
configured as a GPO in Register 0x1D, Register 0x1E,
and Register 0x1F.
2. Set the bit for the row or column that needs to be
configured as a GPO in Register 0x23, Register 0x24,
and Register 0x25.
3. Set the drive level for the GPO lines in Register 0x17,
Register 0x18, and Register 0x19.
Columns or rows configured as GPO are not read into
Register 0x014, Register 0x15, and Register 0x16. The D1
through D11, D22 through D27, and D30 status LED indicate
the level of the GPIOs configured as GPOs.
