• P84/IRQ3/TxD1
The pin function is switched as shown below according to the combination of the TE bit in
SCR of SCI_1, the SPS1 bit*

P84DDR
Pin Function P84 input
Notes: 1. When the IRQ3E bit in IER is set to 1, this pin is used as the IRQ3 input pin.
2. The program development tool (emulator) does not support this function.
• P83/LPCPD
The pin function is switched as shown below according to the state of the P83DDR bit.

Pin Function
Note: When at least one of bits LPC3E to LPC1E is set to 1 in HICR0, this pin is used as the

LPCPD input pin.
• P82/CLKRUN
The pin function is switched as shown below according to the combination of the LPC3E to
LPC1E bits in HICR0, and the P82DDR bit.

Pin Function
Note: * When at least one of bits LPC3E to LPC1E is set to 1in HICR0, the P82DDR should be
cleared to 0.
