A
From Idle mode, the circuit enters the activation mode
when the microcontroller sets the CMDVCC line LOW or
sets the MODE line HIGH when the CMDVCC line is
already LOW. The internal circuitry is then activated, the
internal clock is activated and an activation sequence is
executed. When RST is enabled it becomes the inverse of
RSTIN.
Figures 10 to 12 illustrate the activation sequence as
follows:
