Note
input
1 TO01
output
Note
The ASCK0 and ADTRG pins are alternate-function pins. When using the pin as the ASCK0 pin, disable
the trigger input of the alternate-function ADTRG pin (clear the ADS.TRG bit to 0 or set the ADS.ADTMD bit
to 1). When using the pin as the ADTRG pin, do not set the UART0 operation clock to external input (set
the CKSR0.TPS03 to CKSR0.TPS00 bits to other than 1011).
Caution When the P3n pin is specified as an alternate function by the PMC3.PMC3n bit with the PFC3n
and PFCE3n bits maintaining the initial value (0), output becomes undefined. Therefore, to
specify the P3n pin as an alternate function, set the PFC3n and PFCE3n bits to 1 first and then
set the PMC3n bit to 1 (n = 3, 4).
