Hi!
I am currently developing an electronic board using the microprocessor R32C/118.
For the connection of debuger E8a I found two different types of connections:
and provides a connection by pins P64, P65, P66, P67, P55, P50, CNVss,RESET #
this one provides a connection by pins P29, P30, P31, P32, P39, P44, CNVss,RESET #
My question:
I would like to know which of these connections is good, and if both are possible, what are the features not available while debugging, in the case of using one or the other connection (memory expansion, UART1 ...).
Thank you in advance for attention you pay to my question.
UART1 cannot be used during debugging. If you look in the additional document for E8a describing operation with R32C devices you see that the debugger initilises all UART1 registers.
P50 and P55 are a little different as they are mainly used during software download. So if you put pull-ups on these pins it should work in memory expansion mode.
