| |
| 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. |
