Cautions 1. When accessing "(1) Peripheral Function Registers" via the external MCU interface, the
base address is different from the one when accessing from the Cortex-M3 or DMA.
- When accessing from the CPU or DMA controller
BASE = 4001_0000H
- When accessing via the external MCU interface
BASE = D_0000H
2. When accessing via the external MCU interface, only user RAM and process data RAM
(400E 0F80H – 400E 2FFF) can be accessed in the whole ESC memory area (400E 0000H –
400E 2FFFH).
Remark: Registers listed in this section are accessible from the EtherCAT master and CPU. An
accessible state of respective registers is indicated by the following symbols.
ECAT: Access from the EtherCAT master
R/W, PDI: Access from the CPU
