10.5.5
Port 5 pins also function as the pins for SCI I/Os, A/D converter inputs, interrupt inputs, I
bus control signal I/Os, JTAG inputs, PPG outputs, TPU I/Os, and 8-bit timer I/Os. The
correspondence between the register specification and the pin functions is shown below.
• P53/IRQ3-A/ADTRG0-A/TRST*
Notes: 1. ADTRG0-A input when the EXTRGS bit in ADCR0 is 0, and TRGS1 = TRGS0 = 1.
P53DDR
Pin function
The pin function is switched as shown below according to the combination of bits TRGS1,
TRGS0, and EXTRGS in ADCR_0 of the ADC, bit P53DDR, and bit ITS3 in ITSR of the
interrupt controller.
2. IRQ3-A input when the ITS3 bit in ITSR is 0.
3. TRST input when BSCANE pin = 1 and EMLE = 0 in the 145-pin package.
