Digit Selection
The digit(s) to be programmed are selected as illustrated table below. This function is enabled
with a 21 Hex command at D15~D8 and the appropriate data sequence to select Digit 0 only,
Digit 0 and 1, Digit 0 -2 or digit 0-3 as illustrated in table 4. This programming step is performed
simultaneously with the DECODE / DIRECT DRIVE decision (table 5) which utilizes D7~D4. The
initial state, upon power up, is Digits 0-3 activated.
STAND-BY Commands
Two STAND-BY commands are available as illustrated in table below. STAND-BY / NO DATA
CLEAR places the device in a power save mode while leaving data intact in the various regis-
ters. This mode is enabled by a 4 Hex command at D15~D12 and 0 Hex at D3~D0. D11~D4 are
not relevent in the STAND-BY / NO DATA CLEAR Mode.
STAND-BY / DATA CLEAR also places the device in a power save mode and clears data in the
various registers leaving registers in their initial state. This mode is enabled by a 4 Hex com-
mand at D15~D12 and 1 Hex at D3~D0. D11~D4 are not relevent in the STAND-BY / DATA
CLEAR Mode.
“x” indicates that data is required in this field to execute the function. “-” indicates that data in
this field is not required and not recognized.
