INT1

The following outputs can not be controlled using the IOTST feature: TCA,

RSOC, RDAT[15:0], RXPRTY[1:0], RCA, D[7:0], and TDO.

1. INT corresponds to output INTB. INTB is an open drain output and should be

pulled high for proper operation. Writing a logic one to the INT bit allows the

S/UNI-PLUS to drive INTB low. Writing a logic zero to the INT bit tristates the

INTB output.

2. To control these outputs, RMODE[1:0] should be set to binary '10' in the

Master Configuration Register.

3. To control GTOCLK, TMODE[1:0] should be set to binary '11' in the Master

Configuration Register.

JTAG Test Port

The S/UNI-PLUS JTAG Test Access Port (TAP) allows access to the TAP

controller and the 4 TAP registers: instruction, bypass, device identification and
