M41ST85W
Square Wave Output
The M41ST85W offers the user a programmable
square wave function which is output on the SQW
pin. RS3-RS0 bits located in 13h establish the
square wave output frequency. These frequencies
are listed in
Table 4.
Once the selection of the
SQW frequency has been completed, the SQW
pin can be turned on and off under software con-
trol with the Square Wave Enable Bit (SQWE) lo-
cated in Register 0Ah.
