- 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)
-
- BIT# 15 14 13 12 11 10 09 08 07 06 05 04 03 02 01 00
-JOY0DAT Y7 Y6 Y5 Y4 Y3 Y2 Y1 Y0 X7 X6 X5 X4 X3 X2 X1 X0
-JOY1DAT Y7 Y6 Y5 Y4 Y3 Y2 Y1 Y0 X7 X6 X5 X4 X3 X2 X1 X0
-
- 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:
-
- +-------------------+-----------------------------------------+
- | Serial | Bit Name | Description |
- +--------+----------+-----------------------------------------+
- | 0 | M0H | JOY0DAT Horizontal Clock |
- | 1 | M0HQ | JOY0DAT Horizontal Clock (quadrature) |
- | 2 | M0V | JOY0DAT Vertical Clock |
- | 3 | M0VQ | JOY0DAT Vertical Clock (quadrature) |
- | 4 | M1V | JOY1DAT Horizontal Clock |
- | 5 | M1VQ | JOY1DAT Horizontal Clock (quadrature) |
- | 6 | M1V | JOY1DAT Vertical Clock |
- | 7 | M1VQ | JOY1DAT Vertical Clock (quadrature) |
- +--------+----------+-----------------------------------------+
-
- 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:
-
- +------------+------+---------------------------------+
- | Directions | Pin# | Counter bits |
- +------------+------+---------------------------------+
- | Forward | 1 | Y1 xor Y0 (BIT#09 xor BIT#08) |
- | Left | 3 | Y1 |
- | Back | 2 | X1 xor X0 (BIT#01 xor BIT#00) |
- | Right | 4 | X1 |

- These addresses each read a pair of 8 bit pot counters.
- (4 counters total). The bit assignment for both
- addresses is shown below. The counters are stopped by signals
- from 2 controller connectors (left-right) with 2 pins each.

- 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.
