INT_KEY Key Matrix Interrupt. See Chapter 26, "Keypad Interface".
INT_TOUCH Touch Screen Controller Interrupt. This is the general
interrupt from the TSC. See
Chapter 25 , "Analog Touch
Screen Interface" .
INT_EXT[0] External Interrupt 0.
INT_EXT[1] External Interrupt 1.
INT_EXT[2] External Interrupt 2.
TINTR 64Hz TICK Interrupt. This interrupt becomes active on
every rising edge of the internal 64Hz clock. The 64Hz
clock is derived from a 15-stage ripple counter that divides
the 32.768kHz oscillator input down to 1Hz for the real
time clock. This interrupt is cleared by writing any value to
the
“RTCSts” register. See Chapter 20 , "Real Time Clock
With Software Trim"
WEINT Watchdog Expired Interrupt. This interrupt will become
active on a rising edge of the periodic 64Hz tick interrupt
clock if the TICK interrupt (TINT) is still active. That is, if a
tick interrupt has not been serviced for a complete tick
period. Both WEINT and TINT interrupts are cleared by
writing any value to the
“RTCSts” register, see Chapter 20 ,
"Real Time Clock With Software Trim" . Failure to service
this interrupt does not cause a system reset and the action
taken on receipt of this interrupt is system dependent.
INT_RTC Real Time Clock interrupt. See Chapter 20 , "Real Time
Clock With Software Trim" .
INT_IrDA IrDA Interrupt. See Chapter 17 , "IrDA" .
INT_MAC Ethernet MAC Interrupt. See Chapter 9 , "1/10/100 Mbps
Ethernet LAN Controller" .
INT_PROG Programmable Interrupt. See Chapter 7 , "Raster Engine
With Analog/LCD Integrated Timing and Interface" .
