DESCRIPTION
RxFIFO Overflow Interrupt Enable:
This READ/WRITE bit-field permits the user to either enable or
disable the RxFIFO Overflow Interrupt. If the user enables this
interrupt, then the Receive PPP Packet Processor block will gen-
erate this interrupt anytime the RxFIFO experiences an Overflow
event.
0 - Disables the RxFIFO Overflow Interrupt.
1 - Enables the RxFIFO Overflow Interrupt.
Non-Zero FCS Error Count Interrupt Enable:
This READ/WRITE bit-field permits the user to either enable or
disable the Non-Zero FCS Error Count Interrupt. If the user
enables this interrupt, then the Receive PPP Packet Processor
block will generate an interrupt anytime the Receive PPP Packet
Processor - FCS Error Count Registers are incremented from
the value "0x00000000" to a "non-zero" value.
0 - Disables the Non-Zero FCS Error Count Interrupt.
1 - Enables the Non-Zero FCS Error Count Interrupt
Non-Zero Receive ABORT Packet Count Interrupt Enable:
This READ/WRITE bit-field permits the user to either enable or
disable the Non-Zero ABORT Packet Count Interrupt. If the user
enables this interrupt, then the Receive PPP Packet Processor
block will generate an interrupt anytime the Receive PPP Packet
Processor - Aborted Packet Count Registers are incremented
from the value "0x00000000" to a "non-zero" value.
0 - Disables the Non-Zero ABORT Packet Count Interrupt
1 - Enables the Non-Zero ABORT Packet Count Interrupt.
