Normal clocked serial operation.
Timer-synchronized clocked serial operation.
Timer-synchronized clocked serial uses Timer B1.
Timer-synchronized clocked serial uses Timer B2.
Normal clocked serial clock polarity, inactive high. internal or external clock.
Normal clocked serial clock polarity, inactive low. internal clock only.
Inverted clocked serial clock polarity, inactive low. internal or external clock.
Inverted clocked serial clock polarity, inactive high. internal clock only.
These bits are ignored in the clocked serial mode and should be set to zeros.
No effect on transmitter.
Terminate current clocked serial transmission. No effect on buffer.
No effect on receiver.
Terminate current clocked serial reception.
Time constant for the Timer A counter. This time constant will take effect the
next time that the Timer A counter counts down to zero. The timer counts
modulo n + 1, where n is the programmed time constant.
