RX Data Decision Time
The decision point for receiving data, its unit has 1/16 of baud rate.
MAX1 [7:4]
n
Maximum number of “1”s
The maximum number of “1”s to decide the received IrDA (RZ) signal as 0.
If P1 is set to 1, MAX1 has the unit of 1/1843200 sec, or if P1 is set to 0, the
unit of MAX1 has 1/16 of baud rate.
MIN1 [3:0]
n
Minimum number of “1”s
The minimum number of “1”s to decide the received IrDA (RZ) signal as 0.
If P1 is set to 1, MIN1 has the unit of 1/1843200 sec, or if P1 is set to 0, the
unit of MIN1 has 1/16 of baud rate.
