Interrupts
The MT90500 provides a wide variety of interrupt source bits, allowing for easy monitoring of MT90500
operation. All interrupt source bits, including the module level interrupt bits, have an associated mask bit which
enables or disables assertion of the interrupt pin. This enables the user to tailor the interrupt pin activity to the
application. Interrupt source bits are set regardless of the state of the associated mask bit, so even source bits
which are disabled from causing an interrupt pin assertion may be polled by the CPU by reading the
appropriate register.
2.8.1
Module Level Interrupts
The following interrupt bits are used to indicate which MT90500 circuit module is the source of the interrupt.
They are set when one or more interrupt source bits in the particular circuit module is set. The CPU can find
the source of an interrupt by reading the register containing these bits and then reading the indicated module’s
interrupt register.
