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

interrupt generation), then all "Transmit UTOPIA/POS-PHY Inter-

face Block" interrupts will be disabled for interrupt generation. If

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

enable the individual "Transmit UTOPIA/POS-PHY Interface

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

particular interrupt.

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

interrupts within the device.

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

the "Block-Level".

Transmit ATM Cell/PPP Processor Block Interrupt Enable:

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

the Transmit ATM Cell/PPP Processor Block for interrupt genera-

tion. If the user writes a "0" to this register bit and disables the

"Transmit ATM Cell/PPP Processor Block" (for interrupt genera-

tion), then all "Transmit ATM Cell/PPP Processor Block" inter-

rupts will be disabled for interrupt generation. If the user writes a

"1" to this register bit, he/she will still need to enable the individ-

ual "Transmit ATM Cell/PPP Processor Block" interrupt(s) at the

"Source Level" in order to enable that particular interrupt.

0 - Disable all "Transmit ATM Cell/PPP Processor Block" inter-

rupts within the device.

1 - Enables the "Transmit ATM Cell/PPP Processor Block" at the

"Block-Level".
