Section 13 Timer Array Unit B (TAUB)
• When the counter of slave channel 2 reaches 0000
H
, INTTAUBnIm (slave 2)
is generated. The counter of slave channel 3 starts to count down.
• If another INTTAUBnIm (slave 2) is generated while the counter of slave
channel 3 is still counting down, the value of TAUBnCDRm (slave 3) is
reloaded and the counter restarts counting down from this value.
• In the diagram above, the first interrupt on channel 2 occurs while the
counter is counting down, and the second whilst it is counting up.
• After the first interrupt, a slave for which TAUBnTDL.TDLm = 0 waits for
dead time to elapse before setting. However, before the dead time has
elapsed, another interrupt occurs on slave 2, this time while the counter is
counting up. This acts as a reset signal, meaning that a channel for which
TAUBnTDL.TDLm = 0 always remains inactive.
• TAUBnTTOUTm of a slave channel for which TAUBnTDL.TDLm = 1 is set
and reset as normal when the corresponding INTTAUBnIm is generated.
