Appendix F. CCS C Program Function Reference

This is a summary of the more commonly used functions available in CCS C Version 4 (January 2007). For more details on how to use the listed functions and others not included here, visit www.ccsinfo.com for a current manual download.

The following apply to all the following tables:

1. All functions require a header file, e.g., 16F877A.H.

Table F.1. Port Input and Output (Requires Chip Header File Only, e.g., 16F877A.H)

Function	Description	Example	Comment
WRITE BYTE	Write all bits with 8-bit integer	output_A(255);	A replaced by B, C, D, or E
SET BIT	Write output bit high using pin label	output_high(PIN_A0);	A0 replaced by A1, A2, . . ., A7, B0, . . ., B7, etc.
CLEAR BIT	Write output bit low using pin label	output_low(PIN_A0); ...
