SCI-2 not working

Hello,

We are using ST72F561R9.

We have already tested SCI-1 features,

1] Receive with interrupt,

2] Transmit with Polling.

Now we want to test SCI-2, So we Modified the functions written for SCI-1,

to SCI-2, Just by changing the Register names as follows,

1] SCISR => SCI2SR,

2] SCIDR => SCI2DR

3] & more...

But the functions for SCI-2 are not working & there is no Transmition or reception happening on SCI-2 Port.

Q1] We disabled the SCI-2 Receive interrupt & only tested it for Polling

Transmition. But it also did not work. That means the SCI-2 PORT

itself is not acting as a serial port. Is it the case that the serial

port itself is not activated?

Q2] Is there any extra care to be taken to enable SCI-2 than SCI-1?

Regards,

Yogesh/Amit

Hi Yogesh,

please note, that you can/must select the suitable configuration with the option byte 1. For details please see chapter 14.1 Flash Option Bytes of the manual.
