Function
Data Link Bit Transmit (DLX)
PC(1:4).XPC(3:0) = 0110
E1: Marks the S
stream on XDI. The S
slot 0 of every frame not containing the frame
alignment signal are selected by register
XC0.SA8E to XC0.SA4E.
T1/J1: This output provides a 4-kHz signal
which marks the DL-bit position within the data
stream on XDI (in ESF mode only).
Transmit Clock (XCLK)
PC(1:4).XPC(3:0) = 0111
Transmit line clock of 2.048 MHz (E1) or
1.544 MHz (T1/J1) derived from SCLKX/R,
RCLK or generated internally by DCO
circuitries.
Transmit Line Tristate (XLT)
PC(1:4).XPC(3:0) = 1000
A high level on this port sets the transmit lines
XL1/2 or XDOP/N into tristate mode. This pin
function is logically ored with register bit
XPM2.XLT.
