Table D-19
This bit controls whether SRAM operates normally or enters low-power stop mode. In
low-power stop mode, the array retains its contents, but cannot be read or written. This
bit can be read or written at any time.
RLCK defaults to zero on reset; it can be written once to a one, and may be read at
any time.
The RASP field limits access to the SRAM array in microcontrollers that support sep-
arate user and supervisor operating modes. RASP1 has no effect because the CPU16
operates in supervisor mode only. This bit may be read or written at any time. Refer to
Table
0 = SRAM operates normally.
1 = SRAM enters low-power stop mode.
0 = SRAM base address registers can be written.
1 = SRAM base address registers are locked and cannot be modified.
