7.0
The Ayama 10000 device supports the Test Access Port and Boundary Scan Architecture as specified in IEEE JTAG Standard
Number 1149.1. The pin interface to the chip consists of five signals with the standard definitions: TCK, TMS, TDI, TDO, and
TRST_L. Table 7-1 describes the operations that the test access port controller supports, and Table 7-2 describes the TAP Device
ID Register. JTAG can also be reset by driving TMS HIGH, and then holding it for three (3) TCK rising edges.
Note. To disable JTAG functionality, connect the TCK, TMS, and TDI pins to V

Mandatory Sample/Preload. This operation loads the values of signals going to and from I/O pins
Mandatory External Test. This operation uses boundary scan values shifted in from the TAP to test
