S12ZVC SCI 48-pin

[marslin]

There are 2 SCI in S12ZVC. I assigned the RXD0/TXD0  but I can not assign another TXD1/RXD1.

Hi Mars,

Please look at MODRR0 Routing Register. 

SCI0 have these routing options: TXD0 on PJ1; RXD0 on PJ0 as default(0)  OR  TXD0 on PS1; RXD0 on PS0 as non default (1)  
SCI1 have these routing options: TXD1 on PS5; RXD1 on PS4 as default(0) OR  TXD1 on PT1; RXD1 on PT0 as non default (1)

So, you can use two SCI ports (both as non-default routing option) in case of 48LQFP package.

I hope it helps.

Best regards,

Tomas
