TDATI
Input AB4
Framer Transmit Data (TDATI). TDATI contains the
serial data to be transmitted when the TEMAP is
configured as a DS3 framer by setting the
OPMODE[1:0] bits in the Global Configuration register.
TDATI is sampled on the rising edge of TICLK if the
TXGAPEN bit in the DS3 Master Unchannelized
Interface Options register is logic 0. If TXGAPEN is
logic 1, then TDATI is sampled on the rising edge of
TGAPCLK. TDATI can be configured to be sampled on
the falling edge of TICLK or TGAPCLK by setting the
TDATIFALL bit in the DS3 Master Unchannelized
Interface Options register.
This signal shares a signal pin with ED[1] and
MVED[1]. This signal will be TDATI only when enabled
for unchannelized DS3 operation.
TFPI/TMFPI
Input AA3
Framer Transmit Frame Pulse/Multiframe Pulse
(TFPI/TMFPI). TFPI/TMFPI is valid when the TEMAP
is configured as a DS3 framer by setting the
OPMODE[1:0] bits in the Global Configuration register.
TFPI indicates the position of all overhead bits in each
DS3 M-subframe. TFPI is not required to pulse at
every frame boundary.
TMFPI indicates the position of the first bit in each DS3
M-frame. TMFPI is not required to pulse at every
multiframe boundary.
TFPI/TMFPI is sampled on the rising edge of TICLK if
the TXGAPEN bit in the DS3 Master Unchannelized
Interface Options register is logic 0. If TXGAPEN is
logic 1, then TFPI/TMFPI is sampled on the rising edge
of TGAPCLK. TFPI/TMFPI can be configured to be
sampled on the falling edge of TICLK or TGAPCLK by
setting the TDATIFALL bit to 1in the DS3 Master
Unchannelized Interface Options register.
This signal shares a signal pin with ED[2]. This signal
will be TFPI/TMFPI only when enabled for
unchannelized DS3 operation.
