PX3: External interrupt 3 priority high if set
EX3: External interrupt 3 enable if set
IE3: If IT3 = 1, IE3 is set/cleared automatically by hardware when interrupt is detected/serviced
IT3: External interrupt 3 is falling-edge/low-level triggered when this bit is set/cleared by software
PX2: External interrupt 2 priority high if set
EX2: External interrupt 2 enable if set
IE2: If IT2 = 1, IE2 is set/cleared automatically by hardware when interrupt is detected/serviced
IT2: External interrupt 2 is falling-edge/low-level triggered when this bit is set/cleared by software

00: Mode 0. P4.3 is a general purpose I/O port which is the same as Port1.
01: Mode 1. P4.3 is a Read Strobe signal for chip select purpose. The address
range depends on the SFR P43AH, P43AL, P43CMP1 and P43CMP0.
10: Mode 2. P4.3 is a Write Strobe signal for chip select purpose. The address
range depends on the SFR P43AH, P43AL, P43CMP1 and P43CMP0.
11: Mode 3. P4.3 is a Read/Write Strobe signal for chip select purpose. The
address range depends on the SFR P43AH, P43AL, P43CMP1, and
P43CMP0.
