This section describes the timer interface module (TIM4, Version B). The
TIMB is a four-channel timer that provides a timing reference with input
capture, output compare, and pulse-width-modulation functions.

Features of the TIMB include:
Figure 12-1
the TIMB is the 16-bit TIMB counter that can operate as a free-running
counter or a modulo up-counter. The TIMB counter provides the timing
reference for the input capture and output compare functions. The TIMB
counter modulo registers, TBMODH:TBMODL, control the modulo value
of the TIMB counter. Software can read the TIMB counter value at any
time without affecting the counting sequence.
The four TIMB channels are programmable independently as input
capture or output compare channels.
