ON (

Output Flash programming voltage
Note: The S5U1C17001H includes a Flash programming power supply.
When S1C17 processor is selected
Use in conjunction with S5U1C17001C (GNU17 v2.0.0 or later) outputs a variable voltage of 6.0 V to 8.0 V
(max. 100 mA).
When S1C33 processor is selected
Setting SW8 to “On” outputs a fixed voltage of 7.0 V (max. 100 mA).
This must never be used with S1C processors for which usage instructions are not provided in the technical
manual when supplying a voltage as the Flash programming power supply from the S5U1C17001H to the target.
Otherwise, there is a risk of damaging the chip due to overvoltage.
