Table 7
Defines display status; the possibility to
disable the display allows implementation
of blinking under external control.
0 P5 P4 P3 P2 P1 P0 Table 8
Six bits of immediate data, bits P5 to P0,
are transferred to the data pointer to
define one of 32 display RAM addresses.
1 1 0 0 A2 A1 A0 Table 9
Three bits of immediate data, bits A0 to
A2, are transferred to the subaddress
counter to define one of eight hardware
subaddresses.
1 1 1 1 0 I O Table 10 Defines input bank selection (storage of
arriving display data).
Table 11
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.
1 1 1 0 A BF1 BF0 Table 12 Defines the blink frequency.
Table 13
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
