17.14 Debug Module/JTAG Signals
The MCF5307 complies with the IEEE 1149.1a JTAG testing standard. JTAG test pins are
multiplexed with background debug pins. Except for TCK, these signals are selected by the
value of MTMOD0. If MTMOD0 is high, JTAG signals are chosen; if it is low, debug
module signals are chosen. MTMOD0 should be changed only while RSTI is asserted.
17.14.1 Test Reset/Development Serial Clock
If MTMOD0 is high, TRST is selected. TRST asynchronously resets the internal JTAG
controller to the test logic reset state, causing the JTAG instruction register to choose the
bypass instruction. When this occurs, JTAG logic is benign and does not interfere with
normal MCF5307 functionality.
Although TRST is asynchronous, Motorola recommends that it makes an
asserted-to-negated transition only while TMS is held high. TRST has an internal pull-up
resistor so if it is not driven low, it defaults to a logic level of 1. If TRST is not used, it can
be tied to ground or, if TCK is clocked, to V
.
