(4) Description of UART boot program operation
The boot program receives data that is sent from the PC by UART, and loads it to
internal RAM.
If the transferring terminates normally, it calculates SUM and sends the result to
the PC before staring to execute the user program. The starting address to execute is
the address received first . This boot program enables user's own on-board
programming.
a)
Operation procedure
1.
Connect the serial cable . Make sure to perform connection before resetting
the micro controller.
2.
Set both AM1 and AM0 pins to "1" and reset the micro controller.
3.
The receive data in the first byte is the matching data. When the boot
program starts, it goes to a state in which it waits for the matching data to be
received. Upon receiving the matching data, it automatically adjusts the
serial channels' initial baud rate to 9600 bps. The matching data is 5AH.
4.
The second byte is used to echo back 5AH to the PC upon completion of the
automatic baud rate setting in the first byte. If the device fails in automatic
baud rate setting, it goes to an idle state.
5.
The third through sixth bytes are used to send the boot program's version
management information in ASCII code. The PC should check that the
correct version of the boot program is used.
