Summary: Clears the specified pin.
Description: Clears the specified pin to logic ‘
0’.
Precondition: This pin must be previously configured as an output via a
ConfigureIO or
ConfigureIoDefaultOutput call.
Parameters:
pin - The pin number to set (0-7).
Returns: This function returns True if the transmission is successful and returns False if the transmission fails.
Remarks: None
TABLE 2-2: CONFIGURATION FUNCTIONS (CONTINUED)
Category and Function Name
Note 1: Prior to any DLL API usage, a call to the InitMCP2200() function is needed. This function is the only
initialization function in the presented DLL.
2: The configuration only needs to be set a single time – it is stored in NVM.
