TFPO

Output

AB11

The Transmit Frame Pulse Output (TFPO) pulses

 

 

 

high for one TCLK cycle every 2430 TCLK cycles

 

 

 

and provides an 8 KHz timing reference. TFPO can

 

 

 

be assigned to any of the four channels using

 

 

 

TFPO_CH[1:0] configuration register bits, with the

 

 

 

restriction that the selected channel must be self-

 

 

 

timed (not in loop-timed or line-loopback modes).

 

 

 

TFPO is updated on the rising edge of TCLK.
