Timer Interface Module B (TIMB)
Functional description
Functional description
Figure 9 shows the structure of the TIMB. The central component of 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 two TIMB channels are programmable independently as input
capture or output compare channels.
TIMB counter
prescaler
The TIMB clock source can be one of the seven prescaler outputs or the
TIMB clock pin, PTD4/TBCLK. The prescaler generates seven clock
rates from the internal bus clock. The prescaler select bits, PS[2:0], in
the TIMB status and control register select the TIMB clock source.
