Description
Description
The paragraph 11.2.7. IRQ Flags states:
IRQ flags are state bits which can be set or cleared by state machines or the system. There are 8 in total: all 8 are visible.
to all state machines, and the lower 4 can also be masked into one of PIO’s interrupt request lines, via the IRQ0_INTE and
IRQ1_INTE control registers.
Which is wrong, since in RP2350 device, IRQ0_INTE contain fields for all 8 not 4
Additionally, the section 11.1.1. Changes from RP2040 also indicates that
IRQ0_INTE and IRQ1_INTE now expose all eight SM IRQ flags to system-level interrupts (not just the lower four).
Summary
Please change that section to correctly describe RP2350 capabilities.
