Stabilizing time a : An interval required to stabilize the f(XIN) oscillation is automatically generated by hardware.
Stabilizing time b : An interval required to stabilize the f(XCIN) oscillation is automatically generated by hardware.
Stabilizing time c : Generate an interval required to stabilize the f(XIN) oscillation in state C or G by software at the
transition D
→C, D→G, H→C, H→G, J→C, or J→G.
Stabilizing time d : Generate an interval required to stabilize the f(XCIN) oscillation in state B, F by software at the
transition A
→B, E→F, A→F, or E→B.
Return input 1: External wakeup signal (P00–P03, P10–P13)
Return input 2: Timer 2 interrupt request flag
Notes 1. MR3=“1”
→The microcomputer starts its operation after counting f(XCIN) clock signal 59 to 70 times.
MR3=“0”
→The microcomputer starts its operation after counting f(XCIN) clock signal 32 to 43 times.
2. When the following 2 conditions are satisfied, the transition A
→E, B→F, A→F, C→F, G→F represented
by “
” can be executed.
(1) VDD = 2.2 V to 5.5 V (One Time PROM version: VDD = 2.5 V to 5.5 V), f(XIN)
≤ 1.0 MHz
(2) VDD = 4.5 V to 5.5 V, f(XIN)
≤ 2.0 MHz
