|
These addresses each read a 16 bit register. These in turn
|
|
are loaded from the MDAT serial stream and are clocked in on
|
|
the rising edge of SCLK. MLD output is used to parallel load
|
|
the external parallel-to-serial converter.This in turn is
|
|
loaded with the 4 quadrature inputs from each of two game
|
|
controller ports (8 total) plus 8 miscellaneous control bits
|
|
which are new for LISA and can be read in upper 8 bits of
|
|
LISAID.
|
|
Register bits are as follows:
|
|
Mouse counter usage (pins 1,3 =Yclock, pins 2,4 =Xclock)
|
|
|

|
|
|
|
0=LEFT CONTROLLER PAIR, 1=RIGHT CONTROLLER PAIR.
|
|
(4 counters total). The bit usage for both left and right
|
|
addresses is shown below. Each 6 bit counter (Y7-Y2,X7-X2) is
|
|
clocked by 2 of the signals input from the mouse serial
|
|
stream. Starting with first bit received:

|
|
|
|
Bits 1 and 0 of each counter (Y1-Y0,X1-X0) may be
|
|
read to determine the state of the related input signal pair.
|
|
This allows these pins to double as joystick switch inputs.
|
|
Joystick switch closures can be deciphered as follows:

With normal (NTSC or PAL) horiz. line rate, the pots will
|
|
give a full scale (FF) reading with about 500kohms in one
|
|
frame time. With proportionally faster horiz line times,
|
|
the counters will count proportionally faster.
|
|
This should be noted when doing variable beam displays.
