QEI Interrupts

Hello all,
I am playing with the LPC1549 and his QEI. It works so far, but one problem I found:
The Interrupt for position compare.
In the datasheet I read:
Interrupts can be enabled to interrupt when the
compare value is less than, equal to, or greater than the current value of the position
register

So I understand, that an interrupt occurs for each, less, equal and greater.
But there is only a flag in the interrupt register for equal.

Am I blind, or have I understand something wrong?

Thank you in advanced,

Bernhard

That's a typo, there's only one option: equal :((

OK, thank you!

So I have to find other tricks. :)
