The RCGCWTIMER register provides software the capability to enable and disable 3264-bit timer
modules in Run mode. When enabled, a module is provided a clock and accesses to module registers
are allowed. When disabled, the clock is disabled to save power and accesses to module registers
generate a bus fault. This register provides the same capability as the legacy Run Mode Clock

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
