Note: The combination of bits not described in the above table must not be used.
7.3.5
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 7.4 summarizes the input pull-up MOS states.

[Legend]
Off:
On/Off: On when the pin is in the input state, P3DDR = 0, and P3PCR = 1; otherwise off.

P30/LAD0
The pin function is switched as shown below according to the combination of the LPC3E to
LPC1E bits in HICR0 of the host interface (LPC) and the P3nDDR bit.
m = 3 to 1: LPC input/output pins (SERIRQ, LCLK, LRESET, LFRAME, LAD3 to LAD0)
n = 7 to 0
Input pull-up MOS is always off.
