Difference B/W RAW Status Reg and Status Reg on LPC3250

What is the difference between interrupt Raw status register and interrupt status register on LPC3250?

Parents
  • If you refer to the LPC32x0 user manual chapter #5 it states for the Raw Status Register:

    ... RSR shows which interrupt sources are active before being masked by the ER.

    whereas it states for the Interrupt status Register:

    ... Status Registers provide information on which interrupts are actually pending, after being masked by the corresponding Enable Register

    Is there something wrong with your copy of the user manual?
