20.5
There are 35 external signals associated with the eTPU engine: 32 channel input/output signals, 2
output disable signals, and a TCRCLK clock input.
20.5.1 Input and Output Channel Signals (TPUCH[31:0]
The channel signal connections for the eTPU engine are described in
Purpose I/O
microcode may be programmed to set the output level of an eTPU channel in one of two manners:
Every eTPU channel input has a digital filter. This filter is designed to filter out noise pulses that
have width less than a specified value. This prevents small noise glitches from being recognized
by the transition detect logic. Any pulses wider than the specified filter width will be passed to the
channel transition detect logic.
20.5.2 Time Base Clock Signal (TCRCLK)
The TCRCLK input signal is used to control the TCR1 and TCR2 time bases. For pulse
accumulator operations TCRCLK can be used as a gate for a counter based on the internal bus
clock divided by eight. For angle operations TCRCLK can be used to get the tooth transition
indications in angle mode. Further details can be found in the eTPU User’s Manual.
20.5.3 Channel Output Disable Signals (LTPUODIS, UTPUODIS)
The eTPU engine has 2 input signals that are used to force the outputs of a group of 16 channels
to an inactive level. When the LTPUODIS signal is asserted, the TPUCH[15:0] outputs (if they are
so configured) are forced to the opposite of the value specified in the ETPU_CnCR[OPOL] bit.
Likewise, when UTPUODIS is asserted, the TPUCH[31:16] outputs are forced to the opposite of
the value in ETPU_CnCR[OPOL]. Therefore, individual channels can be selected to be affected
by the output disable signals, as well as their disabling forced polarity.
Freescale Semiconductor
• By forcing the logic level to a specified value.
• By specifying the logic level output action when a match or transition event occurs.
External Signal Description
Module.” Each eTPU channel has an input/output signal associated with it. The eTPU
Since the MCF5232, MCF5234, and MCF5235 devices only contain
a 16 channel eTPU, the LTPUODIS and UTPUODIS signals control
only eight channels each, TPUCH[7:0] and TPUCH[15:8]
respectively.
