SERPER contains the baud-rate divider bits. According to the Hardware
Reference Manual, if you consider the value to be N, then N+1 279.4
ns hardware clocks occur between samples of the state of the input
pin.
I understand the MIDI baud rate to be 31250. By this, I calculate that
there are about 114.5 279.4 ns periods per bit transmitted, yielding a
SERPER value of 113 or 114. They both seem to work. Which is best or
is there a different, better value?
