I am trying to understand how bootloaders work and was reading the
PIC18 datasheets for how one would write to program memory.

1. I understand that you can only erase memory in rows of 64 bytes is
that correct?
2. The bootloader described in AN851 says

"For the PIC18F devices, commands 1 through 3 support operations to
FLASH program memory. Read operations occur at the byte level. Write
operations are performed on multiples of 8 bytes (one block). Erase
operations are performed on 64 bytes (one row)."

Does this mean that program memory can be written in 8 byte chunks?

Any pointers appreciated.

Thanks
Mike
