1. Input range specified for regulation. When an external regulator is used, should be tied to
2. Output current is total regulator output, including any current required by the

1. 512 bytes at location 0x3E00 to 0x3FFF are not available for program storage
2. For devices with a Date Code prior to 1040, the programming time over the C2 interface is twice as long. See
3. Duration of write time is largely dependent on VIO voltage, supply voltage, and residual charge on the VPP
