Special STM register semantics provide synchronous views of the entire 56-bit counter,
or 32-bit subsets at different levels of resolution.
The maximum clock period is 2
28.56 years before overflowing. Thus, it is capable of continuously timing the entire
expected product life time of a system without overflowing.
In case of a power-on reset, a watchdog reset, or a software reset, the STM is reset. After
one of these reset conditions, the STM is enabled and immediately starts counting up. It
is not possible to affect the content of the timer during normal operation of the TC1167.
The timer registers can only be read but not written to.
The STM can be optionally disabled for power-saving purposes, or suspended for
debugging purposes via its clock control register. In suspend mode of the TC1167
(initiated by writing an appropriate value to STM_CLC register), the STM clock is
stopped but all registers are still readable.
Due to the 56-bit width of the STM, it is not possible to read its entire content with one
instruction. It needs to be read with two load instructions. Since the timer would continue
to count between the two load operations, there is a chance that the two values read are
not consistent (due to possible overflow from the low part of the timer to the high part
between the two read operations). To enable a synchronous and consistent reading of
the STM content, a capture register (STM_CAP) is implemented. It latches the content
of the high part of the STM each time when one of the registers STM_TIM0 to STM_TIM5
is read. Thus, STM_CAP holds the upper value of the timer at exactly the same time
when the lower part is read. The second read operation would then read the content of
the STM_CAP to get the complete timer value.
The content of the 56-bit System Timer can be compared against the content of two
compare values stored in the STM_CMP0 and STM_CMP1 registers. Interrupts can be
generated on a compare match of the STM with the STM_CMP0 or STM_CMP1
registers.

STM registers are reset by an application reset if bit ARSTDIS.STMDIS is cleared. If
bit ARSTDIS.STMDIS is set, the STM is not reset.
