C Language Features
3.2.6 Bit Instructions
Wherever possible, HI-TECH PICC-18 STD will attempt to use the PIC18 bit instructions. For
example, when using a bitwise operator and a mask to alter a bit within an integral type, the compiler
will check the mask value to determine if a bit instruction can achieve the same functionality.
will produce the instruction:
To set or clear individual bits within integral type, the following macros could be used:
To perform the same operation as above, the bitset macro could be employed as follows:
3.2.7 Multi-byte SFRs
Some of the SFRs associated with the PIC18 can be grouped to form multi-byte values, e.g. the
TMRxH and TMRxL register together form a 16-bit timer count value. Depending on the device
and mode of operation, there may be hardware requirements to read these registers correctly, e.g.
