Data Sheet
11.1.2
Timer block 2 includes the two timers T5 (referred to as the auxiliary timer) and T6
(referred to as the core timer), and the 16-bit capture/reload register CAPREL.
Note: The block 2 Timer T5 and Timer T6 can be used by Software only. There exist no
The count direction (Up / Down) must be programmed via software. An overflow/
underflow of core timer T6 is indicated by the output toggle latch T6OTL whose state may
be output on line T6OFL. The auxiliary timer T6 may be reloaded with the contents of
CAPREL.
The toggle bit also supports the concatenation of T6 with auxiliary timer T5, while
concatenation of T6 with other timers is provided through line T6OFL. Triggered by an
external signal, T3IN or T3EUD, the contents of timer T5 can be captured into register
CAPREL, and T5 may optionally be cleared. Both timer T6 and T5 can count up or down,
and the current timer value can be read or modified by the CPU in the non-
bitaddressable SFRs T5 and T6.
external pin for timer T5 and T6. Additional, there is no external pin connected to
register CAPREL, see also Figure 57, page 214.
