Defines LCD drive mode.
Defines LCD bias configuration.
Defines display status; the possibility to
disable the display allows implementation
of blinking under external control.
Six bits of immediate data, bits P5 to P0,
are transferred to the data pointer to
define one of 32 display RAM addresses.
Three bits of immediate data, bits A0 to
A2, 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 blink frequency.
Selects the blink mode; normal operation
with frequency set by BF1, BF0 or blinking
by alternating display RAM banks;
alternating RAM bank blinking does not
apply in 1 : 3 and 1 : 4 multiplex drive
modes.
