Complete the following steps to bootload the MCU:
1. Turn off all power to the circuit.
2. Install the EPROM containing the code to be downloaded.
3. Install the MCU.
4. Select the bootloader function:
a. Open switches S2 and S3 to select the program and verify
function.
b. Open only switch S2 to select only the verify function.
5. Close switch S1.
6. Turn on the VDD power supply.
CAUTION:
Turn on the VDD power supply before turning on the VPP power supply.
7. Turn on the VPP power supply.
8. Open switch S1. The bootloader code begins to execute. If the
PROGRAM function is selected, the PROGRAM LED turns on
during programming. If the VERIFY function is selected, the
VERIFY LED turns on when verification is successful. The
PROGRAM and VERIFY functions take about 10 seconds.
9. Close switch S1.
10. Turn off the VPP power supply.
CAUTION:
Turn off the VPP power supply before turning off the VDD power supply.
11. Turn off the VDD power supply.
3.6.2 EPROM Erasing
The erased state of an EPROM bit is zero. Erase the EPROM by
exposing it to 15 Ws/cm2 of ultraviolet light with a wavelength of 2537
angstroms. Position the ultraviolet light source one inch from the
EPROM. Do not use a shortwave filter.
Cerdip packages have a transparent window for erasing the EPROM
with ultraviolet light. In the windowless PDIP and SOIC packages, the
2104 EPROM bytes function as one-time programmable ROM
(OTPROM).
