(2) Bit rate and pulse width
Table 13-5 lists bit rates, bit rate error tolerances, and pulse width values.
Bit Rate Bit Rate Error Tolerance
(kbits/s) (% of bit rate)
Note 1
115.2 +/– 0.87
Notes 1. At the operation time with f
2. When a digital noise eliminator is used in a microcontroller operating at 1.41 MHz or above.
Caution When using in infrared data transfer mode, set 10H to the baud rate generator control register
0 (BRGC0).
