INTERRUPTS (Cont’d)
INTERRUPT REGISTER 1 (ITRFRE1)
Address: 0008h - Read/Write
Reset Value: 0000 0000 (00h)
Bit 7:0 = ITiE Interrupt Enable
0: I/O pin free for general purpose I/O
1: ITi external interrupt enabled.
Note: The corresponding interrupt is generated
when:
– a rising edge occurs on the IT5/IT6 pins
– a falling edge occurs on the IT1, 2, 3, 4, 7 and 8
INTERRUPT REGISTER 2 (ITRFRE2)
Address: 0039h - Read/Write
Reset Value: 0000 0000 (00h)
Bit 7:6 = CTL[3:2] IT[12:11] Interrupt Sensitivity
These bits are set and cleared by software. They
are used to configure the edge and level sensitivity
of the IT12 and IT11 external interrupt pins (this
means that both must have the same sensitivity).
