Writing 1 to any of the bits enables the corresponding interrupt as a source for IRQ. Bits in the INT_STS register will still reflect the status of the interrupt source regardless of whether the source is enabled as an interrupt in this register. 13 Transmitter Error (TXE). When generated, indicates that the transmitter has encountered an error. Please refer to Section 3.13.7, "Transmitter Errors," on page 46, for a description of the conditions that will cause a TXE. R/WC 0 12-11 Reserved RO - 10 TX Data FIFO Overrun Interrupt (TDFO). Generated when the TX data FIFO is full, and another write is attempted. R/WC 0 9 TX Data FIFO Available Interrupt (TDFA). Generated when the TX data FIFO available space is greater than the programmed level. R/WC 0 8 TX Status FIFO Full Interrupt (TSFF). Generated when the TX Status FIFO is full. R/WC 0 7 TX Status FIFO Level Interrupt (TSFL). Generated when the TX Status FIFO reaches the programmed level. R/WC 0 6 RX Dropped Frame Interrupt (RXDF_INT). This interrupt is issued whenever a receive frame is dropped. R/WC 0 5 Reserved RO - 4 RX Status FIFO Full Interrupt (RSFF). Generated when the RX Status FIFO is full. R/WC 0 3 RX Status FIFO Level Interrupt (RSFL). Generated when the RX Status FIFO reaches the programmed level. R/WC 0 2-0 GPIO [2:0] (GPIOx_INT). Interrupts are generated from the GPIO’s. These interrupts are configured through the GPIO_CFG register. R/WC 000 Offset: 5Ch Size: 32 bits Bits Description Type Default 31 Software Interrupt (SW_INT_EN) R/W 0 30:26 Reserved RO - 25 TX Stopped Interrupt Enable (TXSTOP_INT_EN) R/W 0 24 RX Stopped Interrupt Enable (RXSTOP_INT_EN) R/W 0 23 RX Dropped Frame Counter Halfway Interrupt Enable (RXDFH_INT_EN). R/W 0 22 Reserved RO 0 21 TX IOC Interrupt Enable (TIOC_INT_EN) R/W 0 20 RX DMA Interrupt (RXD_INT). R/W 0 19 GP Timer (GPT_INT_EN) R/W 0 18 PHY (PHY_INT_EN) R/W 0 17 Power Management Event Interrupt Enable (PME_INT_EN) R/W 0 16 TX Status FIFO Overflow (TXSO_EN) R/W 0 15 Receive Watchdog Time-out Interrupt (RWT_INT_EN) R/W 0 14 Receiver Error Interrupt (RXE_INT_EN) R/W 0 13 Transmitter Error Interrupt (TXE_INT_EN) R/W 0 12-11 Reserved RO - 10 TX Data FIFO Overrun Interrupt (TDFO_INT_EN) R/W 0 Bits Description Type Default |
