Dual-Port TPU3 RAM (DPTRAM)
20.3.5
The MISCNT contains the address of the current MISC memory access. This register is read-only. Note
that the naming of the A[31:0] bits represents little-endian bit encoding.
Exiting TPU3 emulation mode or clearing the MISEN bit in the DPTMCR results in the reset of this
register.
20.4
The DPTRAM module has several modes of operation. The following sections describe DPTRAM
operation in each of these modes.
20.4.1
In normal operation, read or write data accesses of 8-, 16-, or 32-bits are supported. Also, in normal
operation, neither TPU3 accesses the array, nor do they have any effect on the operation of the DPTRAM
module.
20.4.2
The DPTRAM array uses a separate power supply IRAMSTBY to provide power to the DPTRAM array
during a power-down phase.
In order to guarantee valid DPTRAM data during power-down, external low voltage inhibit circuitry
(external to the MPC561/MPC563) must be designed to force the RESET pin of the MPC561/MPC563
into the active state before V
to the DPTRAM during power-down.
