Status bit for the V1 comparator (same as V1_OK, see TMUXOUT)
Connects dedicated I/O pins DIO2 and DIO4 through DIO11 as well as input pins PB,
DIO1 and RX to internal resources. If more than one input is connected to the same
resource, the Multiple column in the table below specifies how they are combined.
Programs the direction of DIO pins 7 through 1. 1 indicates an output. The bits are
ignored if the pin is not configured as DIO. See DIO_PV and DIO_PW for special options
for DIO6 and DIO7. See DIO_EEX[1:0] for special options for DIO4 and DIO5.
Programs the direction of DIO pins 15 through 8. 1 indicates an output. The bits are
ignored if the pin is not configured as I/O. See DIO_PX and DIO_PW for special options
for the DIO8 and DIO9 outputs.
Programs the direction of DIO17.
The value on the DIO pins. Pins configured as LCD will read zero. When written, changes
data on pins configured as outputs. Pins configured as LCD or input will ignore writes.
When set, converts DIO4 and DIO5 to interface with external EEPROM. DIO4 becomes
SDCK and DIO5 becomes bi-directional SDATA.
DIO_Rx[2:0]
DIO_EEX[1:0]
DIO_0[7:1] corresponds to DIO7 through DIO1. PB is read on DIO_0[0].
DIO_1[7:0] corresponds to DIO15 through DIO8.
DIO_2[1] corresponds to DIO17.
DIO_3[5:4] corresponds to DIO28 and DIO29.
