Syntax:
HEFWriteWord ( location, data_word_value )
Command Availability:
Available on all PIC micro-controllers with HEFM memory
Explanation:
HEFWriteWord is used to write information, word values, to HEFM, so that it can be accessed in a user program via the HEFReadWord
command.
location presents the location or relative address to write write. A data Word requires 2 HEF Locations, therefore the location will
range from 0 to 126 in steps of 2.
data is the data that is to be written to the HEFM location. This can be a word value or a word variable.
This method writes information to the HEFM given the specific location in the HEFM data storage .
This method is similar to the methods for EEPROM but this method supports Word values.
Example 1:
'... code preamble to select part
'... code to setup serial
'The following example stores a word value in HEFM location 0
HEFWrite( 0, 0x1234)
Example 2:
'... code preamble to select part
'... code to setup serial
'This example will write two word values to two specific locations.
HEFWriteWord (16, 0xAA01)
HEFWriteWord (18, 0xBB02)
If example 2 were displayed on a serial terminal. The result would show, where -- is the existing value.
