Notes:

Assembler output files must be in the Intel hex format (.HEX) in order to be usable by this

programming software.

The PIC

µC supplied has a Configuration Word which is preset to 3FB9H if it is a PIC

16C74JW or 16LC74JW, or to 3FB1H if it is a PIC 16C74AJW or 16LC74AJW. In each

case, this selects the crystal oscillator, disables the watch dog timer, enables the power up

timer and disables code protection. The programming software currently defaults to 3FB1H.

Consult Arizona Microchip Technology for more information on the Configuration Word.

The "blank check" command (B) only looks at the first location. A programmed device will

always have data in this location as it is the program start address.

For each of the commands B,P,R and V the user will be prompted to manually reset the

target

µC, by pressing the reset switch (SW1) on the µC board. This is because PIC

programming always starts from location 0000 and the program counter can only be

incremented.

Pressing A will display the program data in the bottom window, formatted in pages of 48

consecutive locations. Use the <PageUp> and <PageDown> keys to scroll through the

data. Pressing <Esc> will return the user to the >ok prompt.

1.6.4.2 EF8000 Firmware

The PIC

µC is supplied pre-programmed with EF8000 firmware, which is used to convert the

RS232 serial interface into a C-BUS interface. It also executes some of the higher data rate

commands and collects high speed interrupts for pre-processing, before passing these back to

the PC. Its operation is transparent and it is controlled by the ES8000 Windows Application

Software.

1.6.5

Known Bugs in the ES8000 (Version 1.0) Software

The warnings highlighted in Sections 1.6.3.20 and 1.6.3.22 should be followed to prevent any

Windows application failures.
