Function
COUT[1]
Output J3
The controlled output signal #1 (COUT[1]) is a
software programmable output that is controlled
by the COUTx register bit associated with each
tributary in the STM-4 or STM-1 #1 stream.
In outgoing STM-1 (STS-3) interface mode
(OHSMODEB set high), COUT[1] is
synchronized to the STM-1 #1 stream on
OD[7:0] bus. COUT[1] is updated on the rising
edge of SCLK.
In outgoing STM-4 (STS-12) interface mode
(OHSMODEB set low), COUT[1] is synchronized
to the STM-4 stream on OD[7:0] bus. COUT[1]
is updated on the rising edge of HSCLK.
COUT[2]
COUT[3]
Output L20
The controlled output signal #2 (COUT[2]) is a
software programmable output that is controlled
by the COUTx register bit associated with each
tributary in the STM-1 #2 stream.
In outgoing STM-1 (STS-3) interface mode
(OHSMODEB set high), COUT[2] is
synchronized to the OD[15:8] bus. COUT[2] is
updated on the rising edge of SCLK.
In outgoing STM-4 (STS-12) interface mode
(OHSMODEB set low), COUT[2] is invalid.
Output U23 The controlled output signal #3 (COUT[3]) is a
software programmable output that is controlled
by the COUTx register bit associated with each
tributary in the STM-1 #3 stream.
In outgoing STM-1 (STS-3) interface mode
(OHSMODEB set high), COUT[3] is
synchronized to the OD[23:16] bus. COUT[3] is
updated on the rising edge of SCLK.
In outgoing STM-4 (STS-12) interface mode
(OHSMODEB set low), COUT[3] is invalid.
