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 A2 to A0, 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.
