DISPLAY STATUS
MODE
Defines LCD drive mode.
Defines LCD bias configuration.
Defines display status. The possibility to
disable the display allows implementation
of blinking under external control.
Defines power dissipation mode.
Six bits of immediate data, bits P5 to P0,
are transferred to the data pointer to
define one of forty display RAM
addresses.
Three bits of immediate data, bits A0 to
A3, are transferred to the subaddress
counter to define one of eight hardware
subaddresses.
Defines input bank selection (storage of
arriving display data).
Defines output bank selection (retrieval of
LCD display data).
The BANK SELECT command has no
effect in 1 : 3 and 1 : 4 multiplex drive
modes.
Defines the blinking frequency.
Selects the blinking mode; normal
operation with frequency set by BF1, BF0
or blinking by alternation of display RAM
banks. Alternation blinking does not apply
in 1 : 3 and 1 : 4 multiplex drive modes.
