OPTIONS
defines LCD drive mode
defines LCD bias configuration
defines display status; the possibility to
disable the display allows implementation of
blinking under external control
seven bits of immediate data, bits P6 to P0,
are transferred to the data pointer to define
one of eighty 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
