TSC21020F

4153H–AERO–04/07

program and data memory interfaces in a high impedance state. In addition, three-state

controls (DTMS and PMTS) allow an external device to place either the program or data

memory interface in a high impedance state without affecting the other interface and

without halting the TSC21020F unless it requires a memory access from the affected

interface. The three-state controls make it easy for an external cache controller to hold

the TSC21020F off the bus while it updates an external cache memory.

JTAG Test and Emulation

Support

The TSC21020F implements the boundary scan testing provisions specified by IEEE

Standard 1149.1 of the Joint Testing Action Group (JTAG). The TSC21020F's test

access port and On-chip JTAG circuitry is fully compliant with the IEEE 1149.1 specifi-

cation. The test access port enables boundary scan testing of circuitry connected to the

TSC21020F's I/O pins.

The TSC21020F also implements On-chip emulation through the JTAG test access port.

The processor's eight sets of breakpoint range registers enable program execution at

full speed until reaching a desired breakpoint address range. The processor can then

halt and allow reading/writing of all the processor's internal registers and external mem-

ories through the JTAG port.
