Notes: The combination of bits not described in the above table must not be used.
8.4.5
Port 3 has an on-chip input pull-up MOS function that can be controlled by software. This input
pull-up MOS function can be specified as on or off on a bit-by-bit basis.
Table 8.4 summarizes the input pull-up MOS states.

The pin function is switched as shown below according to the combination of the HI12E bit in
SYSCR2, the LPC3E to LPC1E bits in HICR0 of host interface (LPC), the P3nDDR bit, and
operating mode.
m = 3 to 1: LPC input/output pins (SERIRQ, LCLK, LRESET, LFRAME, LAD3 to LAD0)
when at least one of LPC3E to LPC1E is set to 1.
n = 7 to 0
Input pull-up MOS is always off.
