P83 input pin
P83 output pin
LPCPD input pin
When at least one of bits LPC3E to LPC1E is set to 1 in HICR0, this pin is
used as the LPCPD input pin.
The LPCPD input pin can only be used in mode 2 or 3 (EXPE = 0).
The pin function is switched as shown below according to the combination of
bits HI12E and SDE in SYSCR2, bits LPC3E to LPC1E in HICR0, and bit
P82DDR.
Note: * When at least one of bits LPC3E to LPC1E is set to 1, bits HI12E and
P82DDR should be cleared to 0.
