UART1TXINTR1
UART 1 Transmit Interrupt. See Chapter 14, "UART1 With
UART1RXINTR2
UART 2 Receive Interrupt. See Chapter 15, "UART2"”.
UART1TXINTR2
UART 2 Transmit Interrupt. See Chapter 15, "UART2"”.
UART1RXINTR3
UART 3 Receive Interrupt. See Chapter 16, "UART3 With
UART1TXINTR3
UART 3 Transmit Interrupt. See Chapter 16, "UART3 With
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
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
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,
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
INT_IrDA
IrDA Interrupt. See Chapter 17, "IrDA".
INT_MAC
Ethernet MAC Interrupt. See Chapter 9, "1/10/100 Mbps
INT_PROG
Programmable Interrupt. See Chapter 7, "Raster Engine
