ST90158 - MULTIFUNCTION TIMER (MFT)
MULTIFUNCTION TIMER (Cont’d)
For a configuration where TxOUTA is driven by the
Over/Underflow and by Compare 0, and TxOUTB
is driven by the Over/Underflow and by Compare
1. OACR is programmed with TxOUTA preset to
“0”. OUF sets TxOUTA while CM0 resets it, and
CM1 has no effect. OBCR is programmed with Tx-
OUTB preset to “1”. OUF toggles TxOUTB, CM1
sets it and CM0 has no effect.
Output Waveform Samples In Biload Mode
TxOUTA is programmed to monitor the two time
intervals, t1 and t2, of the Biload Mode, while Tx-
OUTB is independent of the Over/Underflow and
is driven by the different values of Compare 0 and
Compare 1. OACR is programmed with TxOUTA
preset to “0”. OUF toggles the output and CM0 and
CM1 do not affect TxOUTA. OBCR is programmed
with TxOUTB preset to “0”. OUF has no effect,
while CM1 resets TxOUTB and CM0 sets it.
Depending on the CM1/CM0 values, three differ-
ent sample waveforms have been drawn based on
the above mentioned configuration of OBCR. In
the last case, with a different programmed value of
OBCR, only Compare 0 drives TxOUTB, toggling
the output.
For a configuration where TxOUTA is driven by the
Over/Underflow and by Compare 0, and TxOUTB
is driven by Compare 0 and 1. OACR is pro-
grammed with TxOUTA preset to “0”. OUF sets
TxOUTA, CM0 resets it and CM1 has no effect.
OBCR is programmed with TxOUTB preset to “0”.
OUF has no effect, CM0 sets TxOUTB and CM1
toggles it.
OACR = [101100X0]
OBCR = [000111X0]
