read_program_memory( )
read_external_memory( )
Syntax:
READ_PROGRAM_MEMORY ( address , dataptr , count );
READ_EXTERNAL_MEMORY ( address , dataptr , count );
Parameters: address is 16 bits on PCM parts and 32 bits on PCH parts . The least significant
bit should always be 0 in PCM.
dataptr is a pointer to one or more bytes.
count is a 8 bit integer on PIC16 and 16-bit for PIC18

read_high_speed_adc( )
Syntax:
read_high_speed_adc( pair , mode , result) ;
read_high_speed_adc( pair , result );
read_high_speed_adc( pair );
read_high_speed_adc( mode , result );
read_high_speed_adc( result );
read_high_speed_adc();
// Individual start and read or
// read only
// Individual start and read
// Individual start only
// Global start and read or
// read only
// Global start and read
// Global start only
Parameters: pair – Optional parameter that determines which ADC pair number to start and/or
read. Valid values are 0 to total number of ADC pairs. 0 starts and/or reads ADC
pair AN0 and AN1, 1 starts and/or reads ADC pair AN2 and AN3, etc. If omitted
then a global start and/or read will be performed.
