(4) TB0IN noise filter
The input signal of pin TB0IN has the noise filter. The ON/OFF of noise filter and selection of filter clock
are set by bits 2 to 4 of the peripheral mode register.
Note: When using the noise filter, set bit 7 of the peripheral mode register according to the main clock
frequency.

Nothing is assigned.
In an attempt to write to this bit, write “0.” The value, if read, turns out to be
indeterminate.
