18.4.2.4.1
The XGATE 64 Kbyte memory space allows access to internal resources only (Registers, RAM, and
FLASH). The 2 Kilobyte register address range is the same register address range as for the CPU and the
BDM module . XGATE can access the FLASH in single chip modes, even when the MCU is secured. In
expanded modes, XGATE can not access the FLASH when MCU is secured.
The local address of the XGATE RAM access is translated to the global RAM address range. The XGATE
shares the RAM resource with the CPU and the BDM module . The local address of the XGATE FLASH
access is translated to the global address as shown in Figure 18-24. For the implemented memory spaces
and addresses please refer to
