EOnCE Event 2
After PORESET is deasserted, you can configure EE2 as an input (default) or an output.
See the Emulation and Debug chapter in the SC140 DSP Core Reference Manual for
details on how to configure this pin.
Enable Address Event Detection Channel 2 or generate one of the EOnCE events or
enable the Event Counter.
Detection by Address Event Detection Channel 2. Used to trigger external debugging
equipment.
EOnCE Event 3
After PORESET is deasserted, you can configure EE3 as an input (default) or an output.
See the Emulation and Debug chapter in the SC140 DSP Core Reference Manual for
details on how to configure this pin, as well as information on the ERCV Register.
Enable Address Event Detection Channel 3 or generate one of the EOnCE events.
EOnCE Receive Register (ERCV) was read by the DSP. Used to trigger external
debugging equipment.
Boot Mode 0–1
Determines the MSC8101 boot mode when PORESET is deasserted. See the
Emulation and Debug chapter in the SC140 DSP Core Reference Manual for details on
how to set these pins.
EOnCE Event 4
After PORESET is deasserted, you can configure EE4 as an input (default) or an output.
See the Emulation and Debug chapter in the SC140 DSP Core Reference Manual for
details on how to configure this pin, as well as information on the ETRSMT Register.
Enable Address Event Detection Channel 4 or generate one of the EOnCE events
EOnCE Transmit Register (ETRSMT) was written by the DSP. Used to trigger external
debugging equipment.
EOnCE Event 5
After PORESET is deasserted, you can configure EE5 as an input (default) or an output.
See the Emulation and Debug chapter in the SC140 DSP Core Reference Manual for
details on how to configure this pin.
Enable Address Event Detection Channel 5.
Detection by Address Event Detection Channel 5. Used to trigger external debugging
equipment.
Enhanced OnCE (EOnCE) Event Detection
After PORESET is deasserted, you can configure EED as an input (default) or output:
See the Emulation and Debug chapter in the SC140 DSP Core Reference Manual for
details on how to configure this pin.
Enable the Data Event Detection Channel.
Detection by the Data Event Detection Channel. Used to trigger external debugging
equipment.
Spare Pins
Leave disconnected for backward compatibility with future revisions of this device.
CLKOUT
The 60x bus clock.
DLL_IN
For synchronization with an external device.
TEST
For test purposes. You must connect it to GND.
