LPC2364 UART 3Issue:
I am using LPC2364 and tested UART0,UART1 with Interrupts.
Its working fine.But if i try to test UART3,its not working(Not receiving
data).
I have tested UART3 tx part without interrupts based.Its working.
But i didn't test RX part without interrupts method.Is there any limitation
in LPC2364 uart3 interrupts or RX part.
I have also enabled power for UART3 by using PCONP.
REG_PCONP |= 1<<25;
REG_PINSEL1 |= 0x003C0000;
Please share your knowlwdge??
UARt0,uart1 working fine.Same type of code
using for UART3 also.But not working.
Thanks in advance.

Hi
I had a quick look at the manual and I understand that for the LPC2364, its REG_PINSEL9 that controls the UART3 functions.
REG_PINSEL9 |= 0x0F000000

Hi
Can anyone verify this please?
I had a look at the manual and its PINSEL9 that controls UART3 for the 2364 not PINSEL1?

Seems to me it is both. T/RXD3 can be configured into P0.25/26 as well
as into P4.28/29.

Why who NXP do such a things?
Is there any reasons for this?

Guys,
Thanks for your info.I am looking interrupt enable code.Because
After configure,IER register,I didnt get Transmit interrupt.
Thanks,

They do it so that other peripherals won't be excluded when one peripheral is chosen. Pin sharing...
Look at the EINTx signals for the LPC2148. They map all over the place and you pick the pins depending on what you can do without.
EINT0 on the LPC2148 maps to P0.1 and if this is chosen, TXD0 is lost. It also maps to P0.16 which wipes out the capture and match 0.2 possibilities for timer0.
There is almost never going to be a situation where I can do without TXD0 but I suppose I can use P0.16 and lose the timer IO.
Maybe I don't even use EINT0 because of unfavorable mapping and I use EINT1 instead.

OK , I give up !!!!!
How can we help this guy.
Is there an example code that will solve this problem. It's not a big deal..
