I Transmitter Turn On for Channel _0

Hardware mode

Setting this pin "High" turns on the Transmit and Receive Sections of Chan-

nel _0. When TXON_0 = “0” then TTIP_0 and TRING_0 driver outputs will

be tri-stated.

In Host mode

The TXON_n bits in the channel control registers turn each channel Trans-

mit and Receive section ON or OFF. However, control of the on/off function

can be transferred to the Hardware pins by setting the TXONCNTL bit (bit

7) to “1” in the register at address hex 0x82.
