Info

x is a C variable or a constant Purpose: If the id is already known as a C variable then this will locate the variable at address x. In this case the variable type does not change from the original definition. If the id is not known a new C variable is created and placed at address x with the type int16 Warning: In both cases memory at x is not exclusive to this variable. Other variables may be located at the same location. In fact when x is a variable, then id and x share the same memory location. Examples: Example Files: Also See: #word data = 0x0800 struct { int lowerByte : 8; int upperByte : 8; } control_word; #word control_word = 0x85 ... control_word.upperByte = 0x42; None #bit, #byte, #locate, #reserve, Named Registers, Type Specifiers, Type Qualifiers, Enumerated Types, Structures & Unions, Typedef #zero_ram Syntax: Elements: Purpose: Examples: #ZERO_RAM None This directive zero's out all of the internal registers that may be used to hold variables before program execution begins. #zero_ram void main() { } Example Files: Also See: ex_cust.c None 150
BUILT-IN FUNCTIONS BUILT-IN FUNCTIONS The <strong>CCS</strong> compiler provides a lot of built-in functions to access and use the PIC microcontroller's peripherals. This makes it very easy for the users to configure and use the peripherals without going into in depth details of the registers associated with the functionality. The functions categorized by the peripherals associated with them are listed on the next page. Click on the function name to get a complete description and parameter and return value descriptions.
