Function

TDATI[3]

TDATI[2]

TDATI[1]

Input

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

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

TFPI/TMFPI[3]

TFPI/TMFPI[2]

TFPI/TMFPI[1]

Input

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.
