21.4.6
The XEBI does not support any user-controlled options for reducing power consumption.
21.4.6.1
The XEBI does not support any options for reducing power in run mode.
Power consumption is reduced in single-chip modes due to the absence of the external bus interface.
Operation in expanded modes results in a higher power consumption, however any unnecessary toggling
of external bus signals is reduced to the lowest indispensable activity by holding the previous states
between external accesses.
21.4.6.2
The XEBI does not support any options for reducing power in wait mode.
21.4.6.3
The XEBI will cease to function in stop mode.
21.5
This section describes the external bus interface usage and timing. Typical customer operating modes are
normal expanded mode and emulation modes, specifically to be used in emulator applications. Taking the
availability of the external wait feature into account the use cases are divided into four scenarios:
Normal single-chip mode and special single-chip mode do not have an external bus. Special test mode is
used for factory test only. Therefore, these modes are omitted here.
All timing diagrams referred to throughout this section are available in the Electrical Characteristics
appendix of the SoC section.
