Interrupt Controller
The interrupt controller and its associated registers allow the
user’s code to respond to an interrupt from almost every
functional block in the CYRF69213 devices. The registers
associated with the interrupt controller allow interrupts to be
disabled either globally or individually. The registers also
provide a mechanism by which a user may clear all pending
and posted interrupts, or clear individual posted or pending
interrupts.
The following table lists all interrupts and the priorities that are
available in the CYRF69213.
Architectural Description
An interrupt is posted when its interrupt conditions occur. This
results in the flip-flop in
Figure 19
clocking in a ‘1’. The
interrupt will remain posted until the interrupt is taken or until
it is cleared by writing to the appropriate INT_CLRx register.
A posted interrupt is not pending unless it is enabled by setting
its interrupt mask bit (in the appropriate INT_MSKx register).
All pending interrupts are processed by the Priority Encoder to
determine the highest priority interrupt which will be taken by
the M8C if the Global Interrupt Enable bit is set in the CPU_F
register.
Disabling an interrupt by clearing its interrupt mask bit (in the
INT_MSKx register) does not clear a posted interrupt, nor
does it prevent an interrupt from being posted. It simply
prevents a posted interrupt from becoming pending.
Nested interrupts can be accomplished by re-enabling inter-
rupts inside an interrupt service routine. To do this, set the IE
bit in the Flag Register.
