Can anyone tell me where to get an updated user manual of lpc2114/01?
This new version, according to datasheet, has fractional baud generator
in its uart. No address and information given though. If I assume it's
similar to lpc2368 and initialize it accordingly, the uart receives
many framing errors.

Thanks,

Kerem

LPC2124/01 uart's fractional baud rate generator with

3.5795MHz xtal, no pll, pclk=1/4 cclk, MAM disabled, MAMTIM=7
udlL=2, mulval=11, divaddval=5

for 19200 bps appears to be not working.

if I set udlL=5, mulval=6, divaddval=1 for 9600 bps without changing
anything else, everything appears to be working fine.

Can it be a non-documented bug in the fractional baud gen at low speed
xtals? Any ideas or experiences?

Thanks,

Kerem
