CMOS
TCK: JTAG Test Clock
The clock for the JTAG test is input on this pin. TDI and TMS are sampled on the rising edge
of TCK and TDO is updated on the falling edge of TCK.
If TCK is idle at a low level, all stored-state devices contained in the test logic will indefinitely
retain their state.

TDI: JTAG Test Data Input
The test data is input on this pin. It is clocked into the device on the rising edge of TCK.
TDO

O
CMOS
TDO: JTAG Test Data Output
The test data is output on this pin. It is clocked out of the device on the falling edge of TCK.
TDO pin outputs a high impedance signal except during the process of data scanning.
This pin can indicate the interrupt of T0 selected input clock fail, as determined by the
LOS_FLAG_ON_TDO bit (b6, 0BH). Refer to Chapter 3.8.1 Input Clock Validity for details.
