4.41.1
This section describes the functionality of the die-to-die (D2DIV1) initiator block especially designed for low cost connections
between a microcontroller die (Interface Initiator) and an analog die (Interface Target) located in the same package.
The D2DI block
4.41.1.1
The D2DI is the initiator for a data transfer to and from a target typically located on another die in the same package. It provides
a set of configuration registers and two memory mapped 256 Byte address windows. When writing to a window a transaction is
initiated sending a write command, followed by an 8-bit address and the data byte or word to the target. When reading from a
window a transaction is initiated sending a read command, followed by an 8-bit address to the target. The target then responds
with the data. The basic idea is that a peripheral located on another die, can be addressed like an on-chip peripheral, except for
a small transaction delay.
