Figure 6-18 Overall Control of Signal Source Using SIM_GPSnn Control
In some cases, the user can choose peripheral function between several I/O, each of which have the option
to be programmed to control a specific peripheral function. If the user wishes to use that function, only one
of these I/O must be configured to control that peripheral function. If more than one I/O is configured to
control the peripheral function, the peripheral output signal will fan out to each I/O, but the peripheral input
signal will be the logical OR and AND of all the I/O signals.
Complete lists of I/O muxings are provided in Table 2-3.
The GPSn setting can be altered during normal operation, but a delay must be inserted between the time
when one function is disabled and another function is enabled.
Note:
After reset, all I/O pins are GPIO, except the JTAG pins and the RESET pin.

6.3.16.1
Reserved—Bits 15–13
This bit field is reserved. Each bit must be set to 0.
6.3.16.2
Configure GPIOA6 (GPS_A6)—Bit 12
This field selects the alternate function for GPIOA6.
0 = FAULT0 - PWM FAULT0 Input (default)
1 = TA0 - Timer A0
