Pin Function
P37/SERIRQ, P36/LCLK, P35/LRESET, P34/LFRAME, P33/LAD3, P32/LAD2, P31/LAD1,
P30/LAD0
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), and the P3nDDR bit.
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.

Description
The input pull-up MOS is turned on when a P3PCR
bit is set to 1 in the input port state.
The input pull-up MOS function cannot be used
when the host interface is enabled.
