3.6.5.3 EzPort Clocking
The EzPort module is enabled only when the device is operating in EzPort mode. The
module clocks are active only in this mode. When the device is operating in normal
mode, the EzPort clock is disabled.
No register bits control the ezPort module clock because the clocking is determined by
operating mode.
3.6.6 Mini-FlexBus Configuration
This section summarizes how the module has been configured in the chip. For a
comprehensive description of the module itself, see the module’s dedicated chapter.
3.6.6.1 Mini-FlexBus instantiation information
The chip instantiates the Mini-FlexBus module with 20 address lines, 2 control signals, 8
data lines and 2 chip selects. The full functionality of the Mini-FlexBus is available only
on the 64-pin versions of the chip. The 44-pin and 48-pin versions offer the limited
functionality of the DATA bus for interfacing with peripherals such as graphical displays.
The 32-pin version does not support Mini-FlexBus functionality.
