Timer 2 Toggle Output Preset
This bit allows the programmer to preset the Timer 2 output T2O.
T2TOP = 0, resets the toggle outputs with the write cycle (M2 = 0)
T2TOP = 1, sets toggle outputs with the write cycle (M2 = 1)
Note: If T2R = 1, no output preset is possible

Toggle mode: a Timer 2 compare match toggles the
output flip-flop (M2) –> T2O
Duty cycle burst generator 1: the DCG output signal
(DCG0) is given to the output and gated by the output
flip-flop (M2)
Duty cycle burst generator 2: the DCG output signal
(DCGO) is given to the output and gated by the SSI in-
ternal data output (SO)
Biphase modulator: Timer 2 modulates the SSI internal
data output (SO) to Biphase code
Manchester modulator: Timer 2 modulates the SSI inter-
nal data output (SO) to Manchester code
SSI output: T2O is used directly as SSI internal data
output (SO)
PWM mode: an 8/12-bit PWM mode
Not allowed
