PICmicro microcontrollers
Using PIC16CXXX OTP (PIC12C5XX OTP)(PIC16F8X Flash) MCUs.
Implement ICSP
Following signals are use for In-system programming of PICmicro microcontrollers.
When PICmicro device is programmed, pin MCLR / VPP is driven to approximately 12 V.
RB6 and RB7 signals are used by the PICmicro for In-system programming, therefore target
contents at both minimal and maximal power supply, therefore VDD pin of PICmicro must be
?
This interface corresponds with Microchip application notes TB013, TB017, TB016: How to
TM
These application notes describes requirement for target system with In-system programming
device and ISP programmer.
?
? MCLR / VPP reset / switch to programming mode
? RB6 (GP1) clock
? RB7 (GP0) data input / output
? VDD power supply
? GND ground
?
Therefore, the target system must be isolated from this voltage provided by programmer.
?
system mustn’t affect these signals during In-system programming to avoid programming
errors.
Marginal verify is used after programming. Programmer must verify the program memory
?
isolated from rest of target system during programming.

Attention to multitasking OS's (Windows 95/98/Me/NT/2000/XP). There is needful for regular
running of control program for these B+K PRECISION programmer that printer port, on which
is programmer connected, must be reserved for this programmer only. Otherwise, any other
program must not simultaneously to use (or any way to modify) this printer port.
