2
INT EN
RC0
INTERRUPT ENABLE: When high, enables ALIGN ERR to generate
interrupt. Also DCLR1<2>.
1
INT EN
RC0
INTERRUPT ENABLE: When high, enables CRC ERR to generate interrupt.
Also DCLR1<1>.

INT EN
RC0
INTERRUPT ENABLE: When high, enables RX BUF OVERFLO to generate
interrupt. Also DCLR1<0>.
As shown in Table 14, this register contains the bits that
enable the status bits in DLCR0 to generate interrupts. Bit
4 extends the DMA Request from the next-to-last to the
last transfer cycle. Only bits 7, 3, 2, and 1 can generate
interrupts; the other interrupt enable bits are not used.
As shown in Table 15, this register provides control for
enabling interrupts based on the setting of status bits in
DLCR1, the Receive Status register.
