Function
Framer Transmit Data (TDATI[3:1]). TDATI[3:1]
contain the serial data to be transmitted when the
TEMAP-84 is configured as DS3 framers by setting the
OPMODE_SPEx[2:0] bits in the SPE Configuration
registers. TDATI[3:1] are sampled on the rising edge
of the associated TICLK if the TXGAPEN bit in the
DS3 and E3 Master Unchannelized Interface Options
register is logic 0. If TXGAPEN is logic 1, then
TDATI[3:1] are sampled on the rising edge of
TGAPCLK. TDATI[3:1] can be configured to be
sampled on the falling edge of the associated TICLK or
TGAPCLK by setting the TDATIFALL bit in the DS3
and E3 Master Unchannelized Interface Options
register.
Framer Transmit Frame Pulse/Multiframe Pulse
(TFPI/TMFPI[3:1]). TFPI/TMFPI[3:1] are valid when
the TEMAP-84 is configured as DS3 or E3 framers by
setting the OPMODE_SPEx[2:0] bits in the SPE
Configuration registers.
TFPI[3:1] indicate the position of all overhead bits in
each DS3 M-subframe or the first bit in each G.751 E3
or G.832 E3 frame. TFPI[3:1] are not required to pulse
at every overhead bit.
TMFPI[3:1] indicate the position of the first bit in each
4760-bit DS3 M-frame or the first bit in each E3 frame.
TMFPI[3:1] are not required to pulse at every
multiframe boundary. This is selected by setting the
TXMFPI bit in the DS3 and E3 Master Unchannelized
Interface Options Registers.
TFPI/TMFPI[3:1] are sampled on the rising edge of the
associated TICLK. TDATI[3:1] can be configured to be
sampled on the falling edge of the associated TICLK
by setting the TDATIFALL bit to 1 in the DS3 and E3
Master Unchannelized Interface Options register.
