Dot_List_Reset ($F2DE)

This routine draws a series of dots, specified by the list pointed to by the X register. The list has the following format:

mode, relative y, relative x,

mode, relative y, relative x,

. . .

. . .

mode, relative y, relative x

0x01

 

This routine will continue to traverse the list, until a mode > 0 is encountered; at that point, it will reset the zero reference (the integrators).

ENTRY:

DP = $D0

X-reg points to the dot list

EXIT:

X-reg points to next byte after the terminator

D-reg trashed
