INTERNAL MEMORY
6.8 Connecting to A Serial Programmer
The diagram below shows an example of user system configuration which has had a serial
programmer connected. After the user system is powered on, the serial programmer writes to the
flash memory in clock-synchronized serial mode. No communication problems associated with the
oscillation frequency may occur. If the system uses any 32170 pins which will connect to a serial
programmer, care must be taken to prevent adverse effects on the system when a serial
programmer is connected. Note that the serial programmer uses the addresses H'0000 0084
through H'0000 0093 as an area to check ID for flash memory protection.
Figure 6.8.1 Pin Connection Diagram
Note 1 : Turn on the power to the user system before you write to the flash memory.
Note 2 : If the system circuit uses P83-P87, consideration must be taken for connection of a serial programmer.
Note 3 : P83 must have a high-level signal applied to it.
Note 4 : P64/SBI must be fixed high or low to ensure that interrupts will not be generated.
Note 5 : The pullup resistances of P83, P84, P86, and P87 must be set to suit system design conditions.
Note 6 : The typical pullup resistances of P83, P84, P86, and P87 are 4.7 to 10 k
Ω
.
Note 7 : All other ports, whether high or low, do not affect flash memory programming.
