Timer Interface B (TIMB)
17.1 Introduction
This section describes the timer interface module B (TIMB). The TIMB is a 2-channel timer that provides:

17.2 Features
Features of the TIMB include:
17.3 Functional Description
Figure 17-2
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 two TIMB channels are programmable independently as input capture or output compare channels.
