System Control
Register 29: Micro Direct Memory Access Peripheral Present (PPDMA), offset
0x30C
The PPDMA register provides software information regarding the μDMA module.
Important: This register should be used to determine if the μDMA module is implemented on this
microcontroller. However, to support legacy software, the DC7 register is available. A
read of the DC7 register correctly identifies if the μDMA module is present.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
