Electrical Design Considerations
MOTOROLA
56F802 Technical Data
31
Consider all device loads as well as parasitic capacitance due to PCB traces when calculating
capacitance. This is especially critical in systems with higher capacitive loads that could create
higher transient currents in the VDD and GND circuits.
Take special care to minimize noise levels on the VREF, VDDA and VSSA pins.
Designs that utilize the TRST pin for JTAG port or OnCE module functionality (such as
development or debugging systems) should allow a means to assert TRST whenever RESET is
asserted, as well as a means to assert TRST independently of RESET. TRST must be asserted at
power up for proper operation. Designs that do not require debugging functionality, such as
consumer products, TRST should be tied low.
Because the Flash memory is programmed through the JTAG/OnCE port, designers should provide
an interface to this port to allow in-circuit Flash programming.
