Hi,

I've been reviewing section 29 (instruction set) of this manual
(DS31029A)) and have found a couple of examples that I don't understand.
Perhaps they're errors, but probably not. On pg. 29-29 (MOVF) Example 1:

MOVF  INDF, 0

Before Instruction
    W=  0x17
    FSR=0xC2
Contents of Address (FSR) = 0x00
After Instruction
    W = 0x17
   FSR= 0xC2
Contents of Address (FSR)= 0x00
  Z=1

Is this correct?  If so, why?  What would happen if the instruction had
been: MOVF  INDF, 1 ?
----------------------------------------------

On pg. 29-36 (RLF) and similarly for 29-37 (RRF) we have Example 2

RLF  INDF,1
Before Instruction
  W= xxxx xxxx
  FSR= 0xC2
  Contents of Address (FSR) = 0011 1010
  C=1
After Instruction
  W= 0x17
  FSR= 0xC2
  Contents of Address (FSR) = 0111 0101
  C=0

A few other cases are given where W starts off as unknown and ends up as
0x17.

My question is why does W become 0x17?

Thanks for your help and please respond direct.
