Debugging interface
Four of the eight debugging interface pins are also used as SIO pins. When ROMA[16:12] is set to 11111 on the RESET*
signal rising edge, these pins are used for an external real-time debug system.
When ROMA[16:12] is set to 11110 on the RESET* signal rising edge, these pins operate as SIO pins. Do not set
ROMA[16:12] other than as above. The ROMA[16:12] is pulled up internally.
DRESET*/CTS*
I
Debug reset/clear to send
Functions as the DRESET* signal for an external real-time debug system or as the SIO
CTS* signal.
DCLK
O
Debug clock
DCLK signal for an external real-time debug system.
DBGE*
I
Debugger enable
DBGE* signal for an external real-time debug system.
PCST[2]
O
PC Trace Status [2]
PCST[2] signal for an external real-time debug system.
PCST[1]/SOUT
O
PC trace status [2]
Functions as the PCST[1] signal for an external real-time debug system or as the SIO
data output signal.
PCST[0]/RTS*
O
PC trace status [0]/Request to send
Functions as the PCST[0] signal for an external real-time debug system or as the SIO
RTS* signal.
SDI/SIN
I
Serial data input/Serial input
Functions as the SDI signal for an external real-time debug system or as the SIO data
input signal.
SDAO
O
Serial data and address output
SDAO signal for an external real-time debug system.
Other signals
TEST*
I
Test
Test pin. Leave fixed to high.
