RPC TIMING MODE 16 (cont'd)
NOTES:
1. All voltages are referenced to ground.
2. Maximum operating I
3. Idle mode I
4. Stop mode I
5. Pin capacitance is measured with a test frequency - 1 MHz, t
6. Crystal start-up time is the time required to get the mass of the crystal into vibrational motion from
7.
t
ns, V
connected; RST = XTAL1 = V
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 a worst case specification on this time.
