These in turn 101 are loaded from the MDAT serial stream and are clocked in on 102 the rising edge of SCLK. MLD output is used to parallel load 103 the external parallel-to-serial converter.This in turn is 104 loaded with the 4 quadrature inputs from each of two game 105 controller ports (8 total) plus 8 miscellaneous control bits 106 which are new for LISA and can be read in upper 8 bits of 107 LISAID. 108 109 Register bits are as follows: 110 111 - Mouse counter usage (pins 1,3 =Yclock, pins 2,4 =Xclock) 112 113 ======== === === === === === === === === ====== === === === === === === === 114 BIT# 15 14 13 12 11 10 09 08 07 06 05 04 03 02 01 00 115 ======== === === === === === === === === ====== === === === === === === === 116 JOY0DAT Y7 Y6 Y5 Y4 Y3 Y2 Y1 Y0 X7 X6 X5 X4 X3 X2 X1 X0 117 JOY1DAT Y7 Y6 Y5 Y4 Y3 Y2 Y1 Y0 X7 X6 X5 X4 X3 X2 X1 X0 118 ======== === === === === === === === === ====== === === === === === === === 119 120 0=LEFT CONTROLLER PAIR, 1=RIGHT CONTROLLER PAIR. 121 (4 counters total).
