18.9.9 RAMON ( Deprecated )
Address offset: 0x524
RAM on/off register (this register is retained)
Since this register is deprecated the following substitutions have been made: RAM block 0 is equivalent to
a block comprising RAM0.S0 and RAM0.S1 and RAM block 1 is equivalent to a block comprising RAM1.S0
and RAM1.S1. For new designs it is recommended to use the POWER.RAM-0.POWER and its sibling
registers instead.
