Functions
3.6.2 Function Return Values
Function return values are passed to the calling function as follows:
3.6.2.1 8-Bit Return Values
Eight-bit values are returned from a function in the W register. For example, the function:
will exit with the following code:
3.6.2.2 16-Bit and 32-bit Return Values
16-bit and 32-bit values are returned in temporary memory locations, with the least significant word
in the lowest memory location. For example, the function:
will exit with the following code:
3.6.2.3 Structure Return Values
Composite return values (struct and union) of size 4 bytes or smaller are returned in memory as
with 16-bit and 32-bit return values. For composite return values of greater than 4 bytes in size,
the structure or union is copied into the struct psect. Data is copied using the library routine
structcopy which uses FSR0 for the source address, FSR1 for the destination address and W for
the structure size. For example:
