19.4.3 JTAG Boundary-Scan Register
The MCF5307 model includes an IEEE Standard 1149.1-compliant boundary-scan register
connected between TDI and TDO when the EXTEST or SAMPLE/PRELOAD instructions
are selected. This register captures signal data on the input pins, forces fixed values on the
output pins, and selects the direction and drive characteristics (a logic value or high
impedance) of the bidirectional and three-state pins. Table 19-4 shows MCF5307
boundary-scan register bits.
