Unlock detectable by program
• Frequency measurement
• AMIFC pin: for 450 kHz count
• FMIFC pin: for 450 kHz/10.7 MHz count
• HALT mode
• STOP mode
• Reset by RESET pin
• Reset by power-on clear circuit (3-value detection)
• Detection of less than 4.5 V^Note (CPU clock: fX)
• Detection of less than 3.5 V^Note (CPU clock: fX/2 or less and on power
application)
• Detection of less than 2.5 V^Note (in STOP mode)
• VDD = 4.5 to 5.5 V (with PLL operating)
• VDD = 3.5 to 5.5 V (with CPU operating, CPU clock: fX/2 or less)
• VDD = 4.5 to 5.5 V (with CPU operating, CPU clock: fX)
• 80-pin plastic QFP (14 × 14 mm, 0.65 mm pitch)

Note These voltage values are maximum values. The reset is actually executed at a voltage lower than these
values.
