Notes

All these register bits must be set to logic zero for the INTB output to be tri-stated. If any one of these

To enable these outputs, after setting the desired state, RADR[0] must be set to logic zero, RENB must

be set to logic one, bit 4 of register 09BH must be set to logic one, and RFCLK must transition from

logic zero to logic one.

To enable this output, after setting the desired state, RADR[2:0] must be set equal to PHY_ADR[2:0],

RADR[1:0] must be set equal to binary 00, RFCLK must transition from logic zero to logic one.

To enable this output, after setting the desired state, TADR[2:0] must be set equal to PHY_ADR[2:0],

TADR[1:0] must be set equal to binary 00, TFCLK must transition from logic zero to logic one.

Bit 1 of this register must be logic zero.

JTAG Test Port

The S/UNI-JET JTAG Test Access Port (TAP) allows access to the TAP controller and the 4 TAP

registers: instruction, bypass, device identification and boundary scan. TAP enables the

following:

• Reading device input logic levels.

• Forcing device output.

• Identifying the device.

• Bypassing the device scan path.
