IEEE 1149.1 Test Access Port (JTAG)
A second method of using the MCF5253 without the IEEE 1149.1A logic being active is to select Debug
mode by setting TEST[2:0]= 001. The IEEE 1149.1A test controller is now placed in the test-logic-reset
state by the internal assertion of the TRST signal to the controller and the TAP pins function as debug mode
pins. While in JTAG mode, input pins TDI/DSI, TMS/BKPT, and TRST/DSCLK have internal pullups
enabled.
