The UART1 interrupt vector is supposed to be 4BH according to the datasheet (table 16 at page 41). In fact it is 23H, the same as UART0. This has been checked on the DK3300-ELCD board.

Is it a PDF typo, or a silicon bug?

Note: For the non-turbo chip UPSD3234, the UART1 vector is indeed 4BH.

Oops, my mistake. Everything is fine.
