The minimum TCLK pulse width, TCLK
The maximum TCLK frequency is:
PTE3/TCLKB is available as a general-purpose I/O pin when not used
as the TIMB clock input. When the PTE3/TCLKB pin is the TIMB clock
input, it is an input regardless of the state of the DDRE3 bit in data
direction register E.
Each channel I/O pin is programmable independently as an input
capture pin or an output compare pin. PTE4/TCH0B and PTE6/TCH2B
can be configured as buffered output compare or buffered PWM pins.
The following I/O registers control and monitor operation of the TIMB:
