I
Transmit Clock Edge - Hardware Mode
With this pin set to a "High", transmit input data of all channels are sampled at
the rising edge of TCLK_n. With this pin tied "Low", input data are sampled at
the falling edge of TCLK_n.
Microprocessor Type Select Input pin 2 - Host Mode
This pin along with
PTS1 (pin 106) selects the microprocessor type.
SeeNOTE: This pin is internally pulled "Low" with a 50k
resistor.
