Register 0x1014: TUL3 ATM Level 3 Signal Label
ATM[7:0]:
The ATM[7:0] bits are used to check the value of TDAT[31:24] when performing in-band
addressing in POS-PHY Level 3 operation in the transmit direction. When TSX and TENB
are high, the in-band address specifying the channel number is on TDAT[7:0]. In order to
prevent confusion between ATM and POS data, TDAT[31:24] may be used to specify the
data type for the channel.
For channels configured for packet data, TDAT[31:24] may be set to the value specified by
POS[7:0] during in-band addressing. For channels configured for ATM cell data,
TDAT[31:24] may be set to the value specified by ATM[7:0] during in-band addressing.
If a channel is configured for ATM traffic and the value of TDAT[31:24] does not match the
value of ATM[7:0] during in-band addressing, the CAMI bit is set.
