Register Description
EXTERNAL INTERRUPT REGISTER (ITRFRE)
Read/Write
Reset value:00h
Bits [7:6] = Reserved.
Forced by hardware to 0
.
Bit 5 = ITBEDGE
Interrupt B Edge Selection.
This bit is set and cleared by software.
0
Falling edge selected on ITB (default)
1
Rising edge selected on ITB
Bit 4 = ITBLAT
Falling or Rising Edge Detector Latch.
This bit is set by hardware, when a falling or rising edge, depending on the sensitivity, occurs on the
ITB/PA7 pin. An interrupt is generated if ITBITE = 1. It must be cleared by software.
0
No edge detected on ITB (default)
1
Edge detected on ITB
Bit 3 = ITBITE
ITB Interrupt Enable
.
This bit is set and cleared by software.
0
ITB interrupt disabled (default)
1
ITB interrupt enabled
Bit 2 = ITAEDGE
Interrupt A Edge Selection.
This bit is set and cleared by software.
0
Falling edge selected on ITA (default)
1
Rising edge selected on ITA
Bit 1 = ITALAT
Falling or Rising Edge Detector Latch.
This bit is set by hardware when a falling or a rising edge, depending on the sensitivity, occurs on
the ITA/PA6 pin. An interrupt is generated if ITAITE = 1. It must be cleared by software.
0
No edge detected on ITA (default)
1
Edge detected on ITA
Bit 0 = ITAITE
ITA Interrupt Enable
.
This bit is set and cleared by software.
0
ITA interrupt disabled (default)
1
ITA interrupt enabled
