Debug and Test Signals
These signals interface with external I/O to provide processor debug and status signals.
3.18.1
Test Mode
The TEST[2:0] inputs are used for various manufacturing and debug tests. For normal mode TEST [2:1]
should be ways be tied low. TEST0 should be set high for BDM debug mode and set low for JTAG mode.
3.18.2
High Impedance
The assertion of HI_Z will force all output drivers to a high-impedance state. The timing on HI_Z is
independent of the clock.
NOTE
JTAG operation will override the HI_Z pin.
3.18.3
Processor Clock Output
The internal PLL generates this PSTCLK/GPIO51 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/GPIO51 is at the same frequency as the core processor.
3.18.4
Debug Data
The debug data pins, DDATA0/CTS1/SDATA0_SDIO1/GPIO1, DDATA1/RTS1/SDATA2_BS2/GPIO2,
DDATA2/CTS0/GPIO3, and DDATA3/RTS0/GPIO4, are four bits wide. This nibble-wide bus displays
captured processor data and break-point status.
3.18.5
Processor Status
The processor status pins, PST0/GPIO50, PST1/GPIO49, PST2/INTMON/GPIO48, and
PST3/INTMON/GPIO47, indicate the SCF5250 processor status. During debug mode, the timing is
synchronous with the processor clock (PSTCLK) and the status is not related to the current bus transfer.
Table 12 shows the encodings of these signals.
