External Bus Interface (S12XEBIV4)
5.1
This document describes the functionality of the XEBI block controlling the external bus interface.
The XEBI controls the functionality of a non-multiplexed external bus (a.k.a. ‘expansion bus’) in
relationship with the chip operation modes. Dependent on the mode, the external bus can be used for data
exchange with external memory, peripherals or PRU, and provide visibility to the internal bus externally
in combination with an emulator.
