Note 1: Conditional skip instructions execute in 1 cycle if the skip is not taken, 2 cycles if the skip is taken over a
one-word instruction and 3 cycles if the skip is taken over a two-word instruction.
2: This instruction is only available in PIC24F, PIC24H, dsPIC30F, and dsPIC33F devices.
3: This instruction is only available in dsPIC33E and PIC24E devices.
4: Compare-branch instructions in dsPIC33E/PIC24E devices execute in 1 cycle if the branch is not taken
and 5 cycles if the branch is taken.
5: In dsPIC33E and PIC24E devices, read and read-modify-write operations on non-CPU Special Function
Registers require an additional cycle when compared to dsPIC30F, dsPIC33F, PIC24F and PIC24H
devices.
