Freescale Semiconductor
System Interface Unit (SIU)
TMCNTSC enables the different TMCNT functions and reports the source of the interrupts. The
register can be read at any time. Status bits are cleared by writing ones; writing zeros does not
affect the value of a status bit.

Once Per Second Interrupt
This status bit is set every second and should
be cleared by software.
ALR
9
0
Alarm Interrupt
This status bit is set when the value of the
TMCNT equals the TMCNTAL value, on the
clock when TMCNT counts to ALARM + 1.

Reserved. Write to zero for future compatibility.
SIE
12
0
Second Interrupt Enable
Specifies whether the time counter generates
an interrupt when SEC is set.
0
The time counter does not generate an
interrupt.
1
The time counter generates an interrupt.
ALE
13
0
Alarm Interrupt Enable
Enables or disables an alarm interrupt.
0
No alarm interrupt.
1 The time counter generates an interrupt
when ALR is set.
TCF
14
0
Time Counter Frequency
The input clock to the time counter may be
either 4 MHz or 32 KHz. The TCF bit should be
set according to the frequency of this clock.
See Section 4.1.2, Timers Clock.
0
The input clock to the time counter is 4
MHz.
1 The input clock to the time counter is 32
KHz.
TCE
15
0
Time Counter Enable
Is not affected by soft or hard reset.
0
The time counter is disabled.
1
The time counter is enabled.
