TCR2 clock/gate control. Part of the TCR2 clocking system. These bits determine the
clock source for TCR2. TCR2 can count on any detected edge of the TCRCLK signal
or use it for gating internal bus clock divided by 8. After reset, TCRCLK signal rising
edge is selected. TCR2 can also be clocked by the internal bus clock divided by 8.
Refer to the eTPU User’s Manual for more information. TCR2 clock sources are listed
in the following table.
TCRCLK signal filter control. Controls the TCRCLK digital filter determining whether
the TCRCLK signal input (after a synchronizer) is filtered with the same filter clock as
the channel input signals or uses the internal bus clock divided by 2, and also whether
the TCRCLK digital filter works in integrator mode or two sample mode. The following
table describes TCRCLK filter clock/mode.
For more information, refer to two sections in the eTPU User’s Manual.

Gated DIV8 clock (internal bus clock / 8). When the
external TCRCLK signal is low, the DIV8 clock is
blocked, preventing it from incrementing TCR2.
When the external TCRCLK signal is high, TCR2 is
incremented at the frequency of the internal bus
clock divided by 8.
