MOTOROLA ANALOG INTEGRATED CIRCUIT DEVICE DATA
Calibration of Timers
In cases where an accurate time base is required, the user
may calibrate the internal timers using the
calibration command
(
Table 8
)
.
After the 33972 device receives the calibration
command, the device expects 512
μ
s logic [0] calibration pulse
on the
CS
terminal. The pulse is used to calibrate the internal
clock. No other SPI terminals should transition during this
512
μ
s calibration pulse. Because the oscillator frequency
changes with temperature, calibration is required for an
accurate time base. Calibrating the timers has no affect on the
quiescent current measurement. The calibration command
simply makes the time base more accurate. The
calibration
command
may be used to update the device on a periodic
basis.
Reset
The reset command resets all registers to Power-ON Reset
(POR) state. Refer to
Table 10
, page 17, for POR states or the
paragraph entitled
Power-ON Reset (POR)
on page 12 of this
datasheet.
