DURATION OF ANALOG SIGNAL SPECIFIED IN BYTE TIMES (8-BIT TIME)
2⁰ + 1 = 2 byte times i.e. (2 ✕ 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 will accept commands after 32,769 byte times. Do not
parallel connect DIO to OUT.
