Functional Description
The following section describes the EBC registers and their settings.
9.3.1
Configuration Register Overview
There are 3 groups of EBC registers:
•
EBC mode registers influencing the global functions.
•
Chip-select-related registers controlling the functionality linked to one CS.
•
MultiCAN and USIC related registers are used to control the access to the internal
LXBus.
CS0 is the default chip-select signal that is active whenever no other chip-select or
internal address space is addressed. Therefore, CS0 has no ADDRSEL register.
Note: All EBC registers are write-protected by the EINIT protection mechanism. Thus,
after execution of the EINIT instruction, these registers are not writable anymore.
A 128-byte address space is occupied/reserved by the EBC.
