This command runs a target connection check and returns the status of the target
connection.
The value is 6bits, where bit 0-2 indicates the status of the short circuit protection
system and bit 4-5 indicates if the ISP is connected correctly to the target system.
Bit 4-5 will only indicate correct target connection if the target is powered.
Bit 3 is “Don’t care”.
Table 3-22. bit descriptions.
The corresponding bit will be set ‘1’ to indicate an error.
That is, if a line is short circuited, if target is not detected or the plug is inserted with a
reverse orientation.
If the value 0x00 is returned it means the connection is ok.
The parameter should be checked before starting a programming sequence to check
if target connection is correct (bit 4-5).
It should also be checked after a programming sequence if the command failed, to
check if the operation failed because of a short circuit.
A short circuit can only be detected after the command Enter Progmode has been
issued, because the control circuits of the STK600 is isolated via switches when the
STK600 is in idle mode.
These commands handles FLASH, EEPROM, fuse bytes, lock bits, signature and
oscillator calibration programming in ISP mode.
