Signal Descriptions

NOTE

JTAG operation will override the HI_Z pin.

8.19.3 Processor Clock Output

The internal PLL generates this PSTCLK/GPO63 and output signal, and is the processor clock output that

is used as the timing reference for the Debug bus timing (DDATA[3:0] and PST[3:0]). The

PSTCLK/GPO63 is at the same frequency as the core processor and cache memory. The frequency will be

twice the bus clock (SCLK) frequency.

8.19.4 Debug Data

The debug data pins, DDATA0_GPIO0, DDATA1_GPIO1, DDATA2_GPIO2, and DDATA3_GPIO4, are

four bits wide. This nibble-wide bus displays captured processor data and break-point status.
