An overview of the MC68306 implementation of IEEE 1149.1 is shown in Figure 7-1. The
MC68306 implementation includes a 16-state controller, a 3-bit instruction register, and
four test registers (a 1-bit bypass register, a 124-bit boundary scan register, a 3-bit module
mode register, and a 32-bit ID register). This implementation includes a dedicated TAP
consisting of the following signals:
7-2
TRST — active low JTAG logic reset (with pullup).
TCK
TMS — test mode select input (with an internal pullup resistor) that is sampled on the
TDI
TDO — three-state test data output that is actively driven in the shift-IR and shift-DR
