11.12.2 __TARGET_DIVIDE_CYCLES16 __TARGET_DIVIDE_CYCLES32

Description:

__TARGET_DIVIDE_CYCLES16 (for 16-bit result instructions) and __TARGET_DIVIDE_CYCLES32 (for 32-bit result instructions) are used in the repeat/divide instruction sequence and resolved based on the selected device's Instruction Set Architecture. Using this symbol in assembly code instead of hard-coding a number helps in porting of code from one device to another.

Examples:

repeat #__TARGET_DIVIDE_CYCLES16
divs.w w2,w4

repeat #__TARGET_DIVIDE_CYCLES32
divs.l w2,w4

Remarks:

The dsPIC33A/PIC32A Programmer’s Reference Manual (DS-70005540), DIV.S instruction behavior section, explains how many cycles the div instruction takes, including the repeat, in its instruction description.

Default Behavior:

The appropriate literal value is assigned based on device instruction set architecture.
