Counter Boundary Registers (CNT_MIN and
CNT_MAX)
These registers
twos-complement, lower and upper boundary values. They can be read
and written at any time. Hardware ensures that reads and write are atomic,
by providing respective shadow registers. This register can be accessed
with either 32-bit or 16-bit operations. This allows for using the GP
counter as a 16-bit counter if sufficient for the application.
