OPTIONS
defines LCD drive mode
defines display status
defines system type
defines pointer to RAM bank
corresponding to the top of the LCD;
useful for scrolling, pseudo-motion and
background preparation of new display
four bits of immediate data, bits
A0 to A3, are transferred to the
subaddress counter to define one of
sixteen hardware subaddresses
defines the auto-increment behaviour of
the address for RAM access
two bits of immediate data, bits Y0 to
Y1, are transferred to the X-address
pointer to define one of forty display
RAM columns
six bits of immediate data, bits
X0 to X5, are transferred to the
X-address pointer to define one of forty
display RAM columns
