Enter Programming Mode
The following algorithm puts the device in Parallel Programming mode:
1.
Apply supply voltage according to Table 29, between V
CC and GND.
2.
Set the RESET and BS pin to “0” and wait at least 100 ns.
3.
Apply 11.5 - 12.5V to RESET. Any activity on BS within 100 ns after +12V has
been applied to RESET will cause the device to fail entering Programming mode.
