* Input voltage: 1= -0.3 to 3.6V, Is =-0.3 to 5.5V
* Output voltage: 0= -0.3 to 3.6V
* Pins 2, 4, 5, 8, 9, 10, 24, 38, 39, 40, and 41 have an internal pull-down resistor (Pd).
Their level is fixed when they are unselected.
* Pins 32 and 33 are input pins for chip address setting when pin 41 is held at the low level.
* Pin 34 serves as the input pin for designating as the master or slave when pin 41 is held at the low level.
* Pin 35 serves as the input pin for configuring the I/O of pins 44 to 47 when pin 41 is held at the low level.
* The DVDD and AVDD pins must be held at the same level and turned on and off at the same timing to preclude latch-up conditions.
