Square Wave Output
The M48T201Y/V offers the user a programmable
square wave function which is output on the SQW
pin. RS3-RS0 Bits located in 7FFF0h establish the
square wave output frequency. These frequencies
are listed in Table 7. 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 7FFF6h.
