S12ZVC SCI

marslin — Tue, 01 Aug 2017 17:55:48 GMT

There are 2 SCI in 12ZVC(48pin). I assign RXD0/TXD0 but can not assign another RXD1/TXD1.

Hi Mars,

The SCI1 at PT0, PT1 pins have the highest priority. So, there should not be any problem with different functions assigned to these pins.

I suppose that issue may be in the code for writing to the MODRR0 register.

This register may be written just once in normal mode. Therefore, you must write complete configuration in a single command.

Correct approach:

MODRR0 = 0x30;‍

Wrong approach:

MODRR0_SCI0 = 1;
MODRR0_SCI1 = 1;
//…‍‍‍

I hope it helps you.

Have a great day,
Radek

Hi,

Did you routed SCI1 to the port (SCI1RR)?

Daniel ,

I mean I can't assign the SCI1 via CodeWarrior Development Studio. There is no SCI1 can be selected.

Hi,

I had to edit this answer, because I cannot asign the SCI1 either on S12ZVC 48-pin package.

The problem has been reported, it should be fixed.

I must have checked 64-pin version instead.

Sorry for the misleading information.

Regards,

Daniel

Hi,

Why does my manual only 1 SCI on S12ZVCA(48-pin)?

Hi Aaron,

You are referring to an outdated version of the RM.
