td(ROC)
Time for internal on-chip oscillator stabilization during powering-on
td(R-S)
STOP release time (Note 2)
td(W-S)
Low power dissipation mode wait mode release time (Note 2)
td(M-L)
Time for internal power supply stabilization when main clock oscillation starts
td(S-R)
Hardware reset 2 release wait time
td(E-A)
Low voltage detection circuit operation start time (Note 3)
Note 1: When V
= 5V
CC
Note 2: This is the time between interrupt for (STOP/WAIT) mode release and resumption of CPU clock operation.
Note 3: After enabling low voltage detection, this time is required before proper detection can occur.
