Change PWM bit depth

The PWM level is currently encoded by a 8 bits value. To increase the number of steps between the minimum and maximum value, the encoding can be changed to 16 bits for instance.

1. In au_plus_top.luc (line 139), change the bit depth to 16:

   pwm pulsewm[NUM_PWM](#TOP(254),#DIV(9),#WIDTH(16));
   dff dutycycle[NUM_PWM][16];
   

2. In au_top.luc (line 189), change the bit depth to 16:

   dutycycle.d[reg.regOut.address-ADDR_PWM] = reg.regOut.data[15:0];
   

Now, the code on the user side should be changed to accept higher values, for instance:

• Micro-Manager device adapter
• Python library
• Java library
