Direct connection
of SCI9 RXD9 and TXD9 of MCU to easyDSP pod is recommended. Please note that
SCI9
should be used
to program flash by easyDSP.
RX and TX pins of easyDSP header are pulled up with 100kOhm
resistor in the pod.
Also
connect easyDSP header #4 pin to
VCC.
Other
considerations :
- In case there is a reset IC
between easyDSP /RESET and MCU RES, it should transfer easyDSP /RESET signal
to MCU RES within 0.5sec.
- In case pull-up
resistor is required, resistor value
should be higher than several k Ohm.
In case you can't use SCI9, you can
use the other SCI channel but only monitoring is available (flash
programming not feasible). In this case let /BOOT and /RESET pins be
open.
