PS[2:0]. (See
minimum TCLK pulse width, TCLK
The maximum TCLK frequency is:
PTE0/TCLKA is available as a general-purpose I/O pin when not used
as the TIMA clock input. When the PTE0/TCLKA pin is the TIMA clock
input, it is an input regardless of the state of the DDRE0 bit in data
direction register E.
Each channel I/O pin is programmable independently as an input
capture pin or an output compare pin. PTE1/TCH0A and PTE2/TCH1A
can be configured as buffered output compare or buffered PWM pins.
The following I/O registers control and monitor operation of the TIM:
