Load Register Selection modes (Table 2)
These modes select the register to provide the data to control the IC operation. The Load Register selection
mode is determined by the settings of D
15
to D
12
and D
11
to D
8
of the shift register.
1. Duty Register
: The data in D
7
to D
0
of this register set the digit output duty cycle.
Duty settings can be made in 16 steps from 0 / 16 to 15 / 16.
(See Table 3)
2. Decode & Digit Register : Sets Decode / No Decode and the number of digits to drive. Decode can be set
using D
7
to D
4
.
The number of digits driven can be set using D
3
to D
0
. Decode / No Decode and
the number of digits driven are set simultaneously.
3. Data registers 0 to 3
: Set the display data corresponding to DIG0 to DIG3 respectively.
D
7
to D
0
of the shift register are used to set the display data.
