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*
2
in SPSR, and the P84DDR bit.

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.
P83DDR 0 1
P83 input pin P83 output pin Pin Function
LPCPD input pin*
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.
LPC3E to LPC1E All 0 Not all 0
P82DDR 0 1 0*
Pin Function P82 input pin P82 output pin CLKRUN I/O pin
Note: * When at least one of bits LPC3E to LPC1E is set to 1in HICR0, the P82DDR should be
cleared to 0.
