Chapter 18 Multiplexed External Bus Interface (MEBIV3)
18.4.5
The MEBI does not contain any user-controlled options for reducing power consumption. The operation
of the MEBI in low-power modes is discussed in the following subsections.
18.4.5.1
The MEBI does not contain any options for reducing power in run mode; however, the external addresses
are conditioned to reduce power in single-chip modes. Expanded bus modes will increase power
consumption.
18.4.5.2
The MEBI does not contain any options for reducing power in wait mode.
18.4.5.3
The MEBI will cease to function after execution of a CPU STOP instruction.

Low-Power Options
Operation in Run Mode
Operation in Wait Mode
Operation in Stop Mode
When the system is operating in a secure mode, internal visibility is not
available (i.e., IVIS = 1 has no effect). Also, the IPIPE signals will not be
visible, regardless of operating mode. IPIPE1–IPIPE0 will display 0es if
they are enabled. In addition, the MOD bits in the MODE control register
cannot be written.
