NOTES:
1. All voltages are referenced to ground.
2. Maximum operating I_CC is measured with all output pins disconnected; XTAL1 driven with t_CLKR,
t_CLKF = 10ns, V_IL = 0.5V; XTAL2 disconnected; EA = RST = PORT0 = V_CC.
3. Idle mode I_CC is measured with all output pins disconnected; XTAL1 driven at 12MHz with t_CLKR,
t_CLKF = 10ns, V_IL = 0.5V; XTAL2 disconnected; EA = PORT0 = V_CC, RST = V_SS.
4. Stop mode I_CC is measured with all output pins disconnected; EA = PORT0 = V_CC; XTAL2 not
connected; RST = V_SS.
5. Crystal startup time is the time required to get the mass of the crystal into vibrational motion from the
time that power is first applied to the circuit until the first clock pulse is produced by the on-chip
oscillator. The user should check with the crystal vendor for the worst-case spec on this time.
6. Assumes V_LI = 3.3V maximum.
7. I_LI is the current drawn from V_LI when V_CC = 0V and V_CCO is disconnected.
8. I _CCO = 10mA.
