Note 4 This parameter (VIH) is not tested on all pins at the same time
Note 5 This specification tests ICC with all power fail circuitry disabled by setting D7 of Interrupt Control Register 1 to 0
Note 6 This specification tests ICC with all power fail circuitry enabled by setting D7 of Interrupt Control Register 1 to 1
Note 7 This specification is tested with both the timers and OSC IN driven by a signal generator Contents of the Test Register e 00(H) the MFO pin is not
configured as buffered oscillator out and MFO T1 INTR are configured as open drain
Note 8 This specification is tested with both the timers off and only OSC IN is driven by a signal generator Contents of the Test Register e 00(H) and the MFO
pin is not configured as buffered oscillator out
