SC140 DSP Core Reference Manual
Emulation and Debug (EOnCE)
EE5DEF
Bit 10
EE5 Definition
—
Programs the EE5 signal.
Programmed as an output of the EOnCE, EE5
can indicate detection by EDCA5, working as
a toggle. Programmed as an input to the
EOnCE, EE5 can be programmed to enable
EDCA5. EE5 cannot disable EDCA5.
0 = Output, detection by EDCA5
1 = Input, enables EDCA5
EE4DEF
Bits 9–8
EE4 Definition
—
Programs the EE4 signal.
Programmed as an output of the EOnCE, EE4
can indicate detection by EDCA4, working as
a toggle. It can also indicate that the ETRSMT
register was written by the core. Programmed
as an input to the EOnCE according to the
programming of the EDU and the ES, EE4 can
be programmed to enable EDCA4 or to
generate one of the EOnCE events. EE4
cannot disable EDCA4.
00 = Output, detection by EDCA4
01 = Output, data in ETRSMT register ready
10 = Reserved
11 = Input, enables EDCA4 or generates an EOnCE
event
EE3DEF
Bits 7–6
EE3 Definition
—
Programs the EE3 signal.
Programmed as an output of the EOnCE, EE3
can indicate detection by EDCA3, working as
a toggle. It can also indicate that the ERCV
register is full. Programmed as an input to the
EOnCE according to the programming of the
EDU and the ES, EE3 can be programmed to
enable EDCA3 or to generate one of the
EOnCE events. EE3 cannot disable EDCA3.
00 = Output, detection by EDCA3
01 = ERCV register full
10 = Reserved
11 = Input, enables EDCA3 or generates an EOnCE
event
EE2DEF
Bits 5–4
EE2 Definition
—
Programs the EE2 signal.
Programmed as an output of the EOnCE, EE2
can indicate detection by EDCA2, working as
a toggle.
Programmed as an input to the EOnCE
according to the programming of the ECNT,
EDU, and ES, EE2 can be programmed to:
Enable the ECNT together with the
ECNTEN bits
Enable the EDCA2 together with the
EDCAEN bits
Generate one of the EOnCE events
together with the ES
EE2 cannot disable EDCA2 or ECNT.
00 = Output, detection by EDCA2
01 = Reserved
10 = Reserved
11 = Input, enables EDCA2 or ECNT, or generates an
EOnCE event
EE1DEF
Bits 3–2
EE1 Definition —
Programs the EE1 signal.
Programmed as an output of the EOnCE, EE4
can indicate detection by EDCA1, working as
a toggle. It can also indicate that the core has
entered debug mode (debug acknowledge). In
the case of debug acknowledge, when
single-stepping, EE1 does not toggle.
Programmed as an input to the EOnCE
according to the programming of the EDU and
the ES, EE1 can be programmed to enable
EDCA1 or to generate one of the EOnCE
events.
00 = Output, detection by EDCA1
01 = Debug acknowledgement
10 = Reserved
11 = Input, enables EDCA1 or generates an EOnCE
event
