In-System
Programming
The on-chip memories and configuration bytes of the AT89C51CC0x parts can be pro-
grammed using the ISP mode of the device.
3.1.1
Manual ISP Mode
3.1.1.1
Board Configuration
To use ISP mode, the board should be configured as follow:
POWER switch (SW1) on “ON” position
EA jumper should be open (internal code execution only).
Before using ISP mode for T89C51CC02 or T89C5115 device, be sure to close SP1
solder pad ( See Section "T89C51CC02/T89C5115 Support (SP1)", page 8).
3.1.1.2
Operating Mode
To enter in ISP mode, press both the RESET (SW5) and ISP (SW4) buttons simulta-
neously. First release the RESET button and then the ISP button. The device enters in
ISP mode.
3.1.2
Auto ISP Mode
The Auto ISP is available only for parts with UART bootloader (-UA devices). It allows
the host PC application (Atmel FLIP software for example) to control the hardware con-
ditions from the serial lines RTS and DTR.
Thus with the Auto ISP mode, the user does not need to push the ISP and RESET
buttons.
3.1.2.1
Board Configuration
To use Auto ISP mode, put the board in the same configuration as ISP mode and also:
Close RTS (JP4) jumper
Close DTR (JP5) jumper
