Click on the Program button in the toolbar:
Programming progress is displayed in the MPLAB Output window.
After a successful programming, if the option is enabled, the serial code is incremented
and a new programming sequence can start.
The PIC16F636 transmitter is a microcontroller-based solution, allowing the firmware
to be adapted for a particular need. The PIC16F636 K

source code must be loaded into MPLAB. The MPLAB K
memory map for the current encoder options to the EEPROM memory. Programming
is done in the usual way, as when programming a microcontroller.

Two different LED flashing rates are available which correspond to different low battery
indication modes.
Enter a 16-bit hex value (0 through FFFF).
This is the initial value of the synchronization counter.
You can opt for the default setting equal to the 10 LSbs of the serial number or enter an
arbitrary 10-bit value (0 through 3FF).
Select between four modes of operation:
No Seed – disables the Seed transmission feature
Limited Seed – disables Seed transmission when the synchronization counter reaches 80
hex (128)
Permanent and Delayed Seed – Seed transmissions are permanently enabled and
delayed
Permanent Seed only – disables the Delayed Seed Transmission function codes
The Seed is a 60-bit value that can be either random (recommended for Secure Learn
methods) or an arbitrary 60-bit value. It will be transmitted in place of the hopping code
and fixed code portions of the code word when the predetermined Seed function code
(button) is activated.
This field determines what function code will produce an immediate or delayed Seed
transmission.
This option allows you to shorten the synchronization header to 3xT
default value is 10xTE
If enabled, this option produces a high output on the S3 pin before data is transmitted
through the DATA pin. The S3 pin will still be available as a button input, but its
de-bouncing and repeat timing functionality will be affected.
