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).
Connects dedicated I/O pins DIO1 through DIO11 as well as input pins PB 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.
*DIO_RRX applies to the RX pin.
Programs the direction of pins DIO7 through DIO1. Writing a 1 indicates an output. A bit
is ignored if the corresponding 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 pins DIO15 through DIO8. Writing a 1 indicates an output.
A bit is ignored if the corresponding pin is not configured as DIO. See DIO_PX and
DIO_PY for special options for the DIO8 and DIO9 outputs.
†
Programs the direction of pins DIO23 through DIO16. Writing a 1 indicates an output.
A bit is ignored if the corresponding pin is not configured as a DIO.
†
The value on DIO pins 56 through 58. The MPU writes data to these registers to change
the data on these pins.
Programs the direction of DIO pins 56 through 58. Writing a 1 indicates an output.
DIO_DIR1[4] controlling DIO12 is only applicable to the 71M6534.
DIO_DIR2[6] controlling DIO22 is only applicable to the 71M6534.
