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.

This allows these pins to double as joystick switch inputs.

With proportionally faster horiz line times, the counters will count proportionally faster. This should be noted when doing variable beam displays. ------------------------------------------------------------------------------- ====== === ==== ==== ====== ================================================ NAME rev ADDR type chip Description ====== === ==== ==== ====== ================================================ POTGO 034 W Paula Pot port (4 bit) bi-direction and data, and pot counter start. ====== === ==== ==== ====== ================================================ ------------------------------------------------------------------------------- ====== === ==== ==== ====== ================================================ NAME rev ADDR type chip Description ====== === ==== ==== ====== ================================================ POTINP 016 R Paula Pot pin data read ====== === ==== ==== ====== ================================================ This register controls a 4 bit bi-direction I/O port that shares the same 4 pins as the 4 pot counters above. +-------+----------+---------------------------------------------+ | BIT# | FUNCTION | DESCRIPTION | +=======+==========+=============================================+ | 15 | OUTRY | Output enable for Paula pin 33 | +-------+----------+---------------------------------------------+ | 14 | DATRY | I/O data Paula pin 33 | +-------+----------+---------------------------------------------+ | 13 | OUTRX | Output enable for Paula pin 32 | +-------+----------+---------------------------------------------+ | 12 | DATRX | I/O data Paula pin 32 | +-------+----------+---------------------------------------------+ | 11 | OUTLY | Out put enable for Paula pin 36 | +-------+----------+---------------------------------------------+ | 10 | DATLY | I/O data Paula pin 36 | +-------+----------+---------------------------------------------+ | 09 | OUTLX | Output enable for Paula pin 35 | +-------+----------+---------------------------------------------+ | 08 | DATLX | I/O data Paula pin 35 | +-------+----------+---------------------------------------------+ | 07-01 | X | Not used | +-------+----------+---------------------------------------------+ | 00 | START | Start pots (dump capacitors,start counters) | +-------+----------+---------------------------------------------+
