Lpc2000

Hi Experts,

i'm currently designing a new project based on the LPC2136. Its my 
first ARM project (and someone gives me not much time...). I am 
coming from AVR and 8051 types. In such projects i always implemented 
RTS/CTS hardware flow control simply by checking the CTS state before 
sending the next characters (there where no FIFOs). 

Now, at first, i thought - nice, use UART1 and everything works 
automatically! But the more i read through the manual the more i come 
to a point where i believe that this still has to be done by software 
(e.g. evaluating an interrupt for the modem status lines, i believe 
it is DELAT-CTS). At the same time the errata sheet states that this 
would not be a good idea when also another interrupt is needed (e.g. 
for the sending).

Another problem is that i never used so called '550 industry 
standard' devices. That means that this UART1 is completely new for 
me.

I must tell that my protocoll does NOT allow simultanously sending 
and receiving of data. Maybe this is helpfull! So i need interrupts 
when sending is ready. I mean, data was completely shifted out, not 
only that the FIFO is empty. But again, the errata sheet states that 
there might also be problems when using the THRE interrupt (by the 
way, is that the right ones for me??). For performance reasons i want 
to use the FIFOs if possible. If not i have to do everything the same 
way as all the years before....

Can anyone help me????

Thanks,
Ünal
