LPC2138 at high speed

LPC2138 at high speed

2005-04-12 by Gus

When I run LPC2138 at speed close to 60Mhz, the chip acts funny! My 
code wouldn't work. The EXACT same code works fine on LPC2114 and on 
10Mhz-LP2138.

Did anyone run LPC2138 at 60Mhz? Is the an errata that I am missing?

Thanks,

Gus

Gus,

did you program MAMTIM to 2 or even 3? That is the only issue that
would come to mind for not working at 60 MHz if MAMTIM = 1
