Figure 17-1. ECCHRS Block Diagram
In order to use this module, other parts of the system must be configured correctly, as described
below.
The ECCHRS signals pass through the External Bus Interface module (EBI) where they are
multiplexed.
The programmer must first configure the I/O Controller to assign the EBI pins corresponding to
the Static Memory Controller (SMC)
sponding to
the I/O Controller.
If the CPU enters a sleep mode that disables clocks used by the ECCHRS, the ECCHRS will
stop functioning and resume operation after the system wakes up from sleep mode.
The clock for the ECCHRS bus interface (CLK_ECCHRS) is generated by the Power Manager.
This clock is enabled at reset, and can be disabled in the Power Manager. It is recommended to
disable the ECCHRS before disabling the clock, to avoid freezing the ECCHRS in an undefined
state.
The ECCHRS interrupt request line is connected to the interrupt controller. Using the ECCHRS
interrupt requires the interrupt controller to be programmed first.
