DESCRIPTION
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".
