Receiver complies and configuration information
such as the maximum power that the Power Receiver
intends to provide at its output. The Power
Transmitter uses this information to create a Power
Transfer Contract.

 Power Transfer : In this phase, the Power
Transmitter continues to provide power to the Power
Receiver. The power Receiver sends the Control
Error Packet for adjusting the Primary Cell current.
The Power Transmitter stops to provide power when
the Received Power Packet is too low to trigger the
FOD function or End Power Transfer Packet is sent
from power Receiver.

Memory Map
The memory mapping of MCU can be divided into 3
blocks, Code, SRAM and Peripheral. Each region has
its recommend usage, and the memory access
behavior could depend on which memory region you
are accessing to.
Code
The size of the code region is 32KB. It is primarily used
to store program code, including the exception vector

table, which is a part of the program image. In OTP
version of chip, the programmable user firmware will be
stored in this area.
SRAM
The SRAM region starts from 0x2000_0000 and the
total access size is 1KB. It’s primarily used to store
data, including stack.
Peripheral
There are 2 peripheral blocks in RT1650, MTP and
peripheral registers. MTP (Multiple Time Programmable
