NOTES: 4. Input current IPP is a maximum of 50 mA only during EPROM programming.
5. Single chip mode, ports configured as inputs or outputs with no load. All inputs ≤ 0.2 V or ≥ VCC – 0.2V.
6. XTAL2/CLKIN is driven with an external square wave signal with 50% duty cycle and rise and fall times less than 10 ns. Current
can be higher with a crystal oscillator. At 5 MHz SYSCLK, this extra current = 0.01 mA x (total load capacitance + crystal capacitance
in pF).
7. Maximum operating current = 7.6 (SYSCLK) + 7 mA.
8. Maximum standby current = 3 (SYSCLK) + 2 mA (OSC POWER bit = 0).
9. Maximum standby current = 2.24 (SYSCLK) + 1.9 mA (OSC POWER bit = 1, only valid up to 3 MHz SYSCLK).
