DEACTIVATION SEQUENCE
When a session is completed, the microcontroller sets the
CMDVCC line to HIGH state or MODE line to LOW state.
The circuit then executes an automatic deactivation
sequence by counting the sequencer down and thus end
in the Idle mode.
Figures 13 and 14 illustrate the deactivation sequence as
follows:
1. RST goes LOW (t11 ≈ t10)
2. CLK is stopped (t12 =t11 + 1⁄2T)
3. I/O, AUX1 and AUX2 fall to zero (t13 =t11 +T)
4. VCC falls to zero (t14 =t11 +11⁄2T); a special circuit
ensures that I/O remains below VCC during the falling
slope of VCC
5. VUP falls (t15 =t11 + 5T).
