Register 4010H: TUPP Misc Test Read Register
This register is used to enable miscellaneous TUPP 2488 test features.
Access to this register is not affected by the Test Mode Address Force functions in registers
4001H and 4002H.
STS48_EN_TST
The STS48_EN_TST bit controls the line side CML configuration of the TUPP 2488 while in
test mode. When STS48_EN_TST is a ‘1’ in test mode the line side CML subsystem is
configured for the STS-48 (2.488 G/Sec) operation
JTAG Test Port
The TUPP JTAG Test Access Port (TAP) allows access to the TAP controller and the 4 TAP
registers: instruction, bypass, device identification and boundary scan. Using the TAP, device
input logic levels can be read, device outputs can be forced, the device can be identified and the
device scan path can be bypassed. For more details on the JTAG port, refer to the Operation
Section (Section 13).
