Blank: Cannot be set.
— : A setting can be made, but an error will result.
* : Continuous transmission/reception is not possible.
Notes: The value set in BRR is given by the following equation:
OSC
N=
(8 × 2 × B)
2n
where
B: Bit rate (bit/s)
N: Baud rate generator BRR setting (0 ≤ N ≤ 255)
OSC: Value of ø
n: Baud rate generator input clock number (n = 0, 2, or 3)
(The relation between n and the clock is shown in table 10-10.)
