Peripheral interface
Peripherals are controlled by the CPU by writing to configuration registers and task registers. Peripheral
events are indicated to the CPU by event registers and interrupts if they are configured for a given event.

15.1 Peripheral ID
Every peripheral is assigned a fixed block of 0x1000 bytes of address space, which is equal to 1024 x 32 bit
registers.
See Instantiation on page 24 for more information about which peripherals are available and where they are
located in the address map.
There is a direct relationship between the peripheral ID and base address. For example, a peripheral with
base address 0x40000000 is assigned ID=0, a peripheral with base address 0x40001000 is assigned ID=1,
and a peripheral with base address 0x4001F000 is assigned ID=31.
Peripherals may share the same ID, which may impose one or more of the following limitations:
• Some peripherals share some registers or other common resources.
• Operation is mutually exclusive. Only one of the peripherals can be used at a time.
• Switching from one peripheral to another must follow a specific pattern (disable the first, then enable the
second peripheral).
15.2 Peripherals with shared ID
In general, and with the exception of ID 0, peripherals sharing an ID and base address may not be used
simultaneously. The user can only enable one at the time on this specific ID.
When switching between two peripherals that share an ID, the user should do the following to prevent
unwanted behavior:
• Disable the previously used peripheral
