IEN1 (0C8H)
Interrupt enable register for DMA and GSC interrupts. A 1 in any bit position enables that interrupt.
IEN1.0 (EGSRV) - Enables the GSC valid receive interrupt.
IEN1.1 (EGSRE) - Enables the GSC receive error interrupt.
IEN1.2 (EDMA0) - Enables the DMA done interrupt for channel 0.
IEN1.3 (EGSTV) - Enables the GSC valid transmit interrupt.
IEN1.4 (EDMA1) - Enables the DMA done interrupt for Channel1.
IEN1.5 (EGSTE) - Enables the GSC transmit error interrupt.
IFS - (0A4H) Interframe Space, determines the number of bit times separating transmitted frames
in CSMA/CD and SDLC.
IP (0B8H)
Allows the user software two levels of prioritization to be assigned to each of the interrupts in IE.
A 1 assigns the corresponding interrupt in IE a higher interrupt than an interrupt with a correspond-
ing 0.
IP.0 (PX0) - Assigns priority of external interrupt,
INT0.
IP.1 (PT0) - Assigns the priority of Timer 0 interrupt, T0.
IP.2 (PX1) - Assigns priority of external interrupt,
INT1.
IP.3 (PT1) - Assigns the priority of Timer1 interrupt, T1.
IP.4 (PS) - Assigns the priority of the LSC interrupt, SBUF.
