Table D-2 displays the GPT address map. The column labeled “Access” indicates the
privilege level at which the CPU must be operating to access the register. A designa-
tion of “S” indicates that supervisor access is required: a designation of “S/U” indicates
that the register can be programmed to the desired privilege level.
GPTMCR bits control freeze, low-power stop, and single-step modes.
Y = M111, where M is the logic state of the module mapping (MM) bit in the SIMCR.
0 = Internal clocks not shut down
1 = Internal clocks shut down
