Description
Control bit for the SEG19/CKOUT pin:
0: The pin is the SEG19 LCD driver
1: The pin is the CK_FIR output (5 MHz in mission mode, 32 kHz in brownout mode)
Status bit for the V1 comparator (same as V1_OK, see TMUXOUT)

– R/W _{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 op-
tions for DIO6 and DIO7. See DIO_EEX for special options for DIO4 and DIO5.
– R/W _{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 op-
tions for the DIO8 and DIO9 outputs.
– R/W Programs the direction of DIO17.

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.
