DS00001875A-page 147 LAN950x 7.3.21 INTERRUPT ENDPOINT CONTROL REGISTER (INT_EP_CTL) This register determines which events cause status to be reported by the interrupt endpoint. See Section 5.3.1.3, "End- point 3 (Interrupt)" for more details. Address: 068h Size: 32 bits Bits Description Type Default 31 Interrupt Endpoint Always On (INTEP_ON) When this bit is set, an interrupt packet will always be sent at the interrupt endpoint interval. 0 = Only allow the transmission of an interrupt packet when an interrupt source is enabled and occurs. 1 = Always transmit an interrupt packet at the interrupt interval. R/W 0b 30:20 RESERVED RO - 19 MAC Reset Time Out (MACRTO_EN) 0 = This event can not cause an interrupt packet to be issued. 1 = This event can cause an interrupt packet to be issued. R/W 0b 18 RX FIFO Has Frame Enable (RX_FIFO_EN) 0 = This event can not cause an interrupt packet to be issued. 1 = This event can cause an interrupt packet to be issued. R/W 0b 17 TX Stopped Enable (TXSTOP_EN) 0 = This event can not cause an interrupt packet to be issued. 1 = This event can cause an interrupt packet to be issued. R/W 0b 16 RX Stopped Enable (RXSTOP_EN) 0 = This event can not cause an interrupt packet to be issued. 1 = This event can cause an interrupt packet to be issued. R/W 0b 15 PHY Interrupt Enable (PHY_EN) 0 = This event can not cause an interrupt packet to be issued. 1 = This event can cause an interrupt packet to be issued. R/W 0b 14 Transmitter Error Enable (TXE_EN) 0 = This event can not cause an interrupt packet to be issued. 1 = This event can cause an interrupt packet to be issued. R/W 0b 13 TX Data FIFO Underrun Interrupt Enable (TDFU_EN) 0 = This event can not cause an interrupt packet to be issued. 1 = This event can cause an interrupt packet to be issued. R/W 0b 12 TX Data FIFO Overrun Interrupt Enable (TDFO_EN) 0 = This event can not cause an interrupt packet to be issued. 1 = This event can cause an interrupt packet to be issued. R/W 0b 11 RX Dropped Frame Interrupt Enable (RXDF_EN) 0 = This event can not cause an interrupt packet to be issued. 1 = This event can cause an interrupt packet to be issued. R/W 0b 10:0 GPIOx Interrupt Enable (GPIOx_EN) 0 = This event can not cause an interrupt packet to be issued. 1 = This event can cause an interrupt packet to be issued. R/W 0b |
