rate control and GPIO[206:207] are fast pad types with drive strength control. The PA bit is not
implemented for this PCR because GPIO is the only pin function.

6.3.1.115 Pad Configuration Registers 206–207 (SIU_PCR206–SIU_PCR207)
The SIU_PCR206–SIU_PCR207 registers control the function, direction, and electrical attributes of
GPIO[206:207]. These registers are separate from the PCR for GPIO[205] since GPIO[206:207] are fast
pad types with drive strength control and GPIO[205] is a medium pad type with slew rate control. The PA
bit is not implemented for these PCRs since GPIO is the only function.
NOTE
The GPIO[206:207] can trigger the ADCs. For ETRIG functionality, set
these pins to GPIO, and then select the GPIO ADC trigger in the
SIU_ETISR register. The input source for each SIN, SS, SCK, and trigger
signal is individually specified in the DSPI input select register
(SIU_DISR).
Refer to Section 6.3.1.161, “eQADC Trigger Input Select Register
(SIU_ETISR).”
