43 / 101 page  Am79C30A/32A Data Sheet 43 D-Channel Mode Register 2 — (DMR2) — Read/Write Address = Indirect 87H DMR2 is used to enable/disable the interrupts generated in the DER (see DER definition on page 41). DMR2 is con- trolled by the microprocessor and does not generate interrupts. DMR2 is defined in Table 40. D-Channel Mode Register 3 — (DMR3) — Read/Write Address = Indirect 8EH Table 40. D-Channel Mode Register 2 Bit Logical 1 Logical 0 (Default Value) 0 Enable Receive Abort interrupt (see DER bit 0) Disable interrupt 1 Enable Non-integer Number of Bytes Received interrupt (see DER bit 1) Disable interrupt 2 Enable Collision Abort Detected interrupt (see DER bit 2) Disable interrupt 3 Enable FCS Error interrupt (see DER bit 3) Disable interrupt 4 Enable Overflow Error interrupt (see DER bit 4) Disable interrupt 5 Enable Underflow Error interrupt (see DER bit 5) Disable interrupt 6 Enable Overrun Error interrupt (see DER bit 6) Disable interrupt 7 Enable Underrun Error interrupt (see DER bit 7) Disable interrupt Table 41. D-Channel Mode Register 3 Bit Logical 1 Logical 0 (Default Value) 0 Enable Valid Address/End of Address interrupt (default value) (see DSR1 bit 0) Disable interrupt 1 Enable End of Valid Transmit Packet interrupt (default value) (see DSR1 bit 6) Disable interrupt 2 Enable Last Byte of Received Packet interrupt (see DSR2 bit 0) Disable interrupt (default value) 3 Enable Receive Byte Available interrupt (see DSR2 bit 1) Disable interrupt (default value) 4 Enable Last Byte Transmitted interrupt (see DSR2 bit 3) Disable interrupt (default value) 5 Enable Transmit buffer Available interrupt (see DSR2 bit 4) Disable interrupt (default value) 6 Enable Received Packet Lost interrupt (see DSR2 bit 2) Disable interrupt (default value) 7 Enable FCS transfer to FIFO Disable FCS transfer to FIFO (default value) |
