Parallel High-Voltage
Programming
The STK526 is compatible with Parallel Programming mode of the STK500. The
embedded RESET circuitry supports the HighVoltage pulses used during programming.
Once the STK526 plugged into the STK500 Expand connectors, the following
configuration must be set before powering the boards :
On the STK526 :
– set the primary power source ( Vcc Src jumper) to STK and REG 5V
– set the 3V3REG jumper must be set to “NOREG”
– mount the jumper STKX1 to enable the STK500 clock signal
On the STK500 :
– connect the PROG_CTRL header (10 pts) to the PORTD header (10pts)
– connect the PROG_DATA header (10 pts) to the PORTB header (10pts)
– mount the following jumpers : VTARGET, RESET, XTAL1, BSEL2
– mount a jumper on the position 1-2 (= right side) of the OSCSEL header
All the Flash memory, EEPROM and all Fuse and Lock Bit options can be programmed
individually or with the sequential automatic programming option.
