In the function, write_program_memory( address, dataptr, count ); is 'address' a word-address or a byte-address? I know it's an int32 and table read/writ ... |

| Yes, by disabling the motor, the problems don't occur. Even then the program reset just once but that was found to be due to the usage of the math function 'pow'. When I replaced it with atan and cos, ... | |

The brownout seems to occur if there is a #fuses NOMCLR. If the MCLR is enabled, only MCLR reset seems to occur and not brownout. If the brownout is also disabled, then there seem ... |
