Timer Count Value
This is the value of the RTOS Timer counter. This is the actual
Timer counter value.
Note:
This register should be read as DWORD. There is no
latching mechanism of the upper bytes implemented, if
the register is accessed as byte/word. Reading the
register as byte/word may not give you true counter
value.
