<strong>RM0090</strong> Ethernet (ETH): media access control (MAC) with DMA controller<br />

Bit 9 RWTIE: receive watchdog timeout interrupt enable<br />

When this bit is set with the abnormal interrupt summary enable bit (ETH_DMAIER<br />

register[15]), the receive watchdog timeout interrupt is enabled.<br />

When this bit is cleared, the receive watchdog timeout interrupt is disabled.<br />

Bit 8 RPSIE: Receive process stopped interrupt enable<br />

When this bit is set with the abnormal interrupt summary enable bit (ETH_DMAIER<br />

register[15]), the receive stopped interrupt is enabled. When this bit is cleared, the receive<br />

stopped interrupt is disabled.<br />

Bit 7 RBUIE: Receive buffer unavailable interrupt enable<br />

When this bit is set with the abnormal interrupt summary enable bit (ETH_DMAIER<br />

register[15]), the receive buffer unavailable interrupt is enabled.<br />

When this bit is cleared, the receive buffer unavailable interrupt is disabled.<br />

Bit 6 RIE: Receive interrupt enable<br />

When this bit is set with the normal interrupt summary enable bit (ETH_DMAIER<br />

register[16]), the receive interrupt is enabled.<br />

When this bit is cleared, the receive interrupt is disabled.<br />

Bit 5 TUIE: Underflow interrupt enable<br />

When this bit is set with the abnormal interrupt summary enable bit (ETH_DMAIER<br />

register[15]), the transmit underflow interrupt is enabled.<br />

When this bit is cleared, the underflow interrupt is disabled.<br />

Bit 4 ROIE: Overflow interrupt enable<br />

When this bit is set with the abnormal interrupt summary enable bit (ETH_DMAIER<br />

register[15]), the receive overflow interrupt is enabled.<br />

When this bit is cleared, the overflow interrupt is disabled.<br />

Bit 3 TJTIE: Transmit jabber timeout interrupt enable<br />

When this bit is set with the abnormal interrupt summary enable bit (ETH_DMAIER<br />

register[15]), the transmit jabber timeout interrupt is enabled.<br />

When this bit is cleared, the transmit jabber timeout interrupt is disabled.<br />

Bit 2 TBUIE: Transmit buffer unavailable interrupt enable<br />

When this bit is set with the normal interrupt summary enable bit (ETH_DMAIER<br />

register[16]), the transmit buffer unavailable interrupt is enabled.<br />

When this bit is cleared, the transmit buffer unavailable interrupt is disabled.<br />

Bit 1 TPSIE: Transmit process stopped interrupt enable<br />

When this bit is set with the abnormal interrupt summary enable bit (ETH_DMAIER<br />

register[15]), the transmission stopped interrupt is enabled.<br />

When this bit is cleared, the transmission stopped interrupt is disabled.<br />

Bit 0 TIE: Transmit interrupt enable<br />

When this bit is set with the normal interrupt summary enable bit (ETH_DMAIER<br />

register[16]), the transmit interrupt is enabled.<br />

When this bit is cleared, the transmit interrupt is disabled.<br />

The Ethernet interrupt is generated only when the TSTS or PMTS bits of the DMA Status<br />

register is asserted with their corresponding interrupt are unmasked, or when the NIS/AIS<br />

Status bit is asserted and the corresponding Interrupt Enable bits (NISE/AISE) are enabled.<br />
