Clock operation
M41T00S
In the event the OF bit is found to be set to '1' at any time other than the initial power-up, the
STOP bit (ST) should be written to a '1,' then immediately reset to '0.' This will restart the
oscillator.
The following conditions can cause the OF bit to be set:
●
The first time power is applied (defaults to a '1' on power-up).
●
The voltage present on VCC is insufficient to support oscillation.
●
The ST bit is set to '1.'
●
External interference of the crystal.
The OF bit will remain set to '1' until written to logic '0.' The oscillator must start and have
run for at least 4 seconds before attempting to reset the OF Bit to '0.'
3.2.3
Output driver pin
When the FT bit is not set, the FT/OUT pin becomes an output driver that reflects the
contents of D7 of the calibration register. In other words, when D7 (OUT Bit) and D6 (FT bit)
of address location 07h are a '0,' then the FT/OUT pin will be driven low.
Note:
The FT/OUT pin is an open drain which requires an external pull-up resistor.
3.2.4
Preferred initial power-on default
Upon initial application of power to the device, the ST and FT bits are set to a '0' state, and
the OF and OUT bits will be set to a '1.' All other register bits will initially power-on in a
random state (see Table 3).
