M41ST84W
Square Wave Output
The M41ST84W offers the user a programmable
square wave function which is output on the SQW
pin. The RS3-RS0 Bits located in 13h establish the
square wave output frequency. These frequencies
are listed in
Table 5.
. 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.
