Timebase Module (TBM)
17.1 Introduction
This section describes the timebase module (TBM). The TBM will generate periodic interrupts at user
selectable rates using a counter clocked by the external crystal clock. This TBM version uses 15 divider
stages, eight of which are user selectable.
17.2 Features
Features of the TBM include:
17.3 Functional Description
This module can generate a periodic interrupt by dividing the clock TBMCLK. The counter is initialized to
all 0s when TBON bit is cleared. The counter, shown in
is set. When the counter overflows at the tap selected by TBR2:TBR0, the TBIF bit gets set. If the TBIE
bit is set, an interrupt request is sent to the CPU. The TBIF flag is cleared by writing a 1 to the TACK bit.
The first time the TBIF flag is set after enabling the timebase module, the interrupt is generated at
approximately half of the overflow period. Subsequent events occur at the exact period.
