The decimal point segment is lit when bit D7 = 1.
sequence is also reset, which might give rise to a one-
time display flicker when the register is written.
Selecting External Components R SET
and C SET to Set Oscillator Frequency
and Segment Current
The RC oscillator uses an external resistor R SET and an
external capacitor C SET to set the oscillator frequency,
f OSC . The allowed range of f OSC is 1MHz to 8MHz.
R SET also sets the peak segment current. The recom-
mended values of R SET and C SET set the oscillator to
4MHz, which makes the blink frequencies 0.5Hz and
1Hz. The recommended value of R SET also sets the
peak current to 40mA, which makes the segment cur-
rent adjustable from 2.5mA to 37.5mA in 2.5mA steps.
I SEG = K I / R SET mA
f OSC = K F / (R SET ? C SET + C STRAY ) MHz
Where:
K I = 2240
