CLK1HZ
1 Hz clock interrupt. See Chapter 20, "Real Time Clock
V_SYNC
Vertical or Composite Sync/Frame Pulse Interrupt. See
INT_VIDEO_FIFO Video FIFO Interrupt. See Chapter 7, "Raster Engine With
INT_SSP1RX
SSP Receive Interrupt. See Chapter 23 "Synchronous
INT_SSP1TX
SSP Transmit Interrupt. See Chapter 23 "Synchronous
TC3UI
Timer Counter 3 Underflow Interrupt. This interrupt
becomes active on the next falling edge of the timer
counter 3 clock after the timer counter has under flowed
(reached zero). The interrupt is cleared by writing any
value to the “Timer3Clear” register. See Chapter 18,
INT_UART1
UART 1 General Interrupt. This interrupt is active if any
UART1 interrupt is active. Interrupt service routines will
need to read the relevant status bits within UART1 to
determine the source of the interrupt. All these sources
are individually maskable within UART1. See Chapter 15,
“UART1”.
SSPINTR
Synchronous Serial Port (SSP) Interrupt. See Chapter 23
INT_UART2
UART 2 General Interrupt. This interrupt is active if any
UART2 interrupt is active. Interrupt service routines will
need to read the relevant status bits within UART2 to
determine the source of the interrupt. All these sources
are individually maskable within UART2. See Chapter 15,
INT_UART3
UART 3 General Interrupt. This interrupt is active if any
UART3 interrupt is active. Interrupt service routines will
need to read the relevant status bits within UART3 to
determine the source of the interrupt. All these sources
are individually maskable within UART3. See Chapter 16,
USHINTR
USB Host Interrupt. See Chapter 11, “USB Host
Controller”.
