56 SBC622 Hardware Reference Manual
3.2.16 Control Register 3 (0x622)
The
SBC622
only
implements
bit
6
of
this
register.
This
controls
the
LEDs.
3.2.17 IRQ Enable Register (0x623)

3.2.19 Timers
The
SBC622
provides
two
32
‐
bit
timers
that
are
completely
dedicated
to
user
applications
and
are
not
required
for
any
standard
system
function.
Each
timer
is
clocked
by
independent
generators
with
selectable
rates
of
2
MHz,
1
MHz,
500
KHz
and
250
KHz.
Each
timer
may
be
independently
enabled
and
each
is
capable
of
generating
a
system
interrupt
on
timeout.
Events
can
be
timed
by
either
polling
the
timers
or
enabling
the
interrupt
capability
of
the
timer.
A
status
register
allows
for
application
software
to
determine
which
timer
is
the
cause
of
any
interrupt.
NOTE
Register definitions exist for four timers (two 16-bit and two 32-bit). The SBC622 only implements
the two 32-bit timers.
