Cell Available signals for transmit ATM cells (active high). When
atmUTxClAv[1] or atmUTxClAv[0] is active one or more complete
cells can be transferred from the ATM layer.
Only atmUTxClAv[0] is used (atmUTxClAv[1] is ignored) when the
DualClavEnb (bit 4) is low (default) in the ATMINTFC register
0xF03. This is the most common configuration.
Start of Cell synchronization signal for transmit ATM cells (active
high). Indicates that the first byte/word of the 53 byte cell is being
placed on the atmUTxData bus.
Data transfer enable(s) for transmit ATM cells (active low).
Indicates that the first byte/word of the 53 byte cell is being placed
on the atmUTxData bus.
Only atmUTxEnb[0] is used (atmUTxEnb[1] will be ignored) when
the DualClavEnb (bit 4) is low (default) in the ATMINTFC register
0xF03. This is most common configuration. When using single
clav mode (DualClavEnb bit is set to 0), atmUTxEnb[1] must be
pulled up.
Clock signal used for transfer of transmit ATM cells from the ATM
Layer. The maximum clock rate is 50 MHz (Note: 33 MHz in TC
Only mode).
Start of Cell synchronization signal for receive ATM cells (active
high). Indicates that the first byte/word of the 53 byte cell is being
placed on the atmURxData bus.
Clock signal used for transfer of receive ATM cells from the ATM
Layer. The maximum clock rate is 50 MHz. (Note: 33 MHz in TC
Only mode).
Cell Available signals for receive ATM cells (active high). When
atmURxClAv[1] or atmURxClaAv[0] is active, one or more
complete cells can be transferred to the ATM Layer.
Only atmURxClAv[0] is used (atmURxClAv[1] is ignored) when the
DualClavEnb (bit 4) is low (default) in the ATMINTFC register
0xF03. This is the most common configuration.
Enable Data transfer and output enable for receive ATM cells
(active low). When using single Clav mode (DualClavEnb, bit4 in
ATMINTFC register 0xF03, is set low), only atmURxEnb[0] is used
and atmURxEnb[1] is not used but must be pulled up. This is most
common configuration.
