Notes: 1. Modes 1 to 3 are not available on the F-ZTAT version.
Modes 2, 3, 6, and 7 are not available on the ROMless version.
2. When this pin is used as an external interrupt input, it should not be
used as an input/output pin with other functions.
PG₀/ADTRG/IRQ6 The pin function is switched as shown below according to the combination of
bits TRGS1 and TRGS0 (trigger select 1 and 0) in the A/D control register
(ADCR).
