Selection Method and Pin Functions
The pin function is switched as shown below according to the combination of
the operating mode, bits TRGS1 and TRGS0 in the A/D control register
(ADCR), and bits IRQPAS, WAITE, WAITPS, BREQOE, BREQOPS, and
P53DDR.
Notes: 1. ADTRG input when TRGS0 = TRGS1 = 1.
The pin function is switched as shown below according to the combination of
bit C/A in the SCI2 SMR, bits CKE0 and CKE1 in SCR, and bits IRQPAS and
P52DDR.
