Interrupts
HMATRIX
Refer to
Table 14-2.
The EBI interface has two interrupt lines connected to the Interrupt Controller:
Handling the EBI interrupt requires configuring the interrupt controller before configuring the EBI.
The EBI interface is connected to the HMATRIX Special Function Register 6 (SFR6). The user
must first write to this HMATRIX.SFR6 to configure the EBI correctly.
