DURATION OF ANALOG SIGNAL SPECIFIED IN BYTE TIMES (8-BIT TIME)
20 + 1 = 2 byte times i.e. (2 x 8)/baud rate
21 + 1 = 3 byte times
22 + 1 = 5 byte times
23 + 1 = 9 byte times
24 + 1 = 17 byte times
25 + 1 = 33 byte times
26 + 1 = 65 byte times
27 + 1 = 129 byte times
28 + 1 = 257 byte times
29 + 1 = 513 byte times
210 + 1 = 1025 byte times
211 + 1 = 2049 byte times
212 + 1 = 4097 byte times
213 + 1 = 8193 byte times
214 + 1 = 16,385 byte times
In this mode OUT is continuous, however DIO accepts commands after 32,769 byte times. Do not parallel
connect DIO to OUT.
