address of the array should be written in a single operation. Writing only one half of the register will
prevent the other half from being written.
20.3.4
The MISRH and MISRL together contain the 32-bit RAM signature calculated by the MISC. These
registers are read-only and should be read by the host when the MISF bit in the MCR is set.
Exiting TPU3 emulation mode results in the reset of both MISRH and MISRL.

DPTRAM array base address. These bits specify the 11 high-order bits of the 24-bit base
address of the DPTRAM array. This allows the array to be placed on a 8-Kbyte boundary
anywhere in the memory map. Do not overlap the DPTRAM array memory map with other
modules on the chip.
On the MPC561/MPC563 the value 0xFFA0 must be used for DPTRAM 6 Kbyte.
Reserved. (Bit 12 represents A[20] in DPTRAM implementations that require it.)
RAM disabled. RAMDS is a read-only status bit. The DPTRAM array is disabled after a master
reset because the RAMBAR register may be incorrect. When the array is disabled, it will not
respond to any addresses on the IMB3. Access to the DPTRAM control register block is not
affected when the array is disabled.
RAMDS is cleared by the DPTRAM module when a base address is written to the array address
field of RAMBAR.
RAMDS = 0: DPTRAM enabled
RAMDS = 1: DPTRAM disabled
