MSP430F5529: UART programming

Part Number: MSP430F5529
Other Parts Discussed in Thread: MSP430F5510

Hi,

I am trying to map the UART port at P4.4,5 with command as below.

P4SEL |= BIT4+BIT5; 
P4MAP5 = 11;
P4MAP4 = 12;

The other initialization bit of UART is set as per example code.

But the UART is not transmitting the data. Is this command is ok for port mapping?

Regards,

Rajesh

    Here is assembler example for my MSP430F5510 UART mapping...

    mov.w #02D52h, PMAPPWD          ; Enable Write-access to modify port mapping
mov.w #PMAPRECFG, PMAPCTL       ; Allow reconfiguration during runtime
mov.b #PM_UCA0RXD, P4MAP4
mov.b #PM_UCA0TXD, P4MAP5
mov.b #PM_UCA1RXD, P4MAP6
mov.b #PM_UCA1TXD, P4MAP7
mov.w #0, PMAPPWD               ; Disable Write-Access to modify port mapping
