Reading data
Drive the AS/DS pin (pin 43) at low level to specify address input.
Specify the address in the lowest seven bits. Set the top bit to 1.
Drive the AS/DS pin (pin 43) at high level to specify data I/O.
Drive the STB pin (pin 44) at high level to cause the LSI to write the data.

1 = 3.7 V
Note: AD0 to AD7 use N-channel open-drain outputs. The standard values for tp
LH
1 and tp
HL
1 are for an output load capacitance of 50 pF, an external
pull to up resistor of 2.7 k
, and an output level of 5.0 V.
