24.1.4 RAM Module Stop Control Registers H and L (RMMSTPCRH, RMMSTPCRL)
RMMSTPCR performs module stop state control of the RAM area. Setting bits MSTP32 to
MSTP39 to 1 stops the corresponding on-chip RAM area. During access to an on-chip RAM area,
do not set bits MSTP32 to MSTP39 corresponding to the area to 1. While bit RAME in SYSCR is
1, and bits MSTP32 to MSTP39 are 1, do not access the corresponding RAM area.
