Notes
1.
External clock signal (frequency = 76.8 kHz, amplitude = V
SS
to V
DD
) at pin EXTAL; OSCPD = HIGH;
test inputs = LOW; other inputs = HIGH; outputs unconnected; SPI transmit enabled; COD bit set to logic 1 (see
Section 8.4.4); to obtain the supply current of an application with a crystal connected as in Fig.19, a typical oscillator
current of 2
