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
reset circuit
?
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.
