R/W

Receive ATM Cell/PPP Packet Processor Block Interrupt

Enable:

This READ/WRITE bit permit the user to either enable or disable

the Receive ATM Cell/PPP Packet Processor Block for interrupt

generation. If the user writes a "0" to this register bit and dis-

ables the Receive ATM Cell/PPP Packet Processor Block (for

interrupt generation), then all Receive ATM Cell/PPP Packet

Processor Block interrupts will be disabled for interrupt genera-

tion. If the user writes a "1" to this register bit, the user will still

need to enable the individual Receive ATM Cell/PPP Packet

Processor Block interrupt(s) at the Source Level in order to

enable that particular interrupt.

0 - Disable all Receive ATM Cell/PPP Packet Processor Block

interrupts within the device.

1 - Enables the Receive ATM Cell/PPP Packet Processor Block

for interrupt generation at the Block-Level.

Transmit UTOPIA/POS-PHY Interface Block Interrupt

Enable:

This READ/WRITE bit permit the user to either enable or disable

the Transmit UTOPIA/POS-PHY Interface Block for interrupt

generation. If the user writes a "0" to this register bit and dis-

ables the Transmit UTOPIA/POS-PHY Interface Block (for inter-

rupt generation), then all Transmit UTOPIA/POS-PHY Interface

Block interrupts will be disabled for interrupt generation. If the

user writes a "1" to this register bit, the user will still need to

enable the individual Transmit UTOPIA/POS-PHY Interface

Block interrupt(s) at the Source Level in order to enable that par-

ticular interrupt.

0 - Disable all Transmit UTOPIA/POS-PHY Interface Block inter-

rupts within the device.

1 - Enables the Transmit UTOPIA/POS-PHY Interface Block at

the Block-Level.
