Input Glitch Filter
Interrupt Timings
Register (IER). The module can be configured to generate an interrupt whenever a pin changes
value, or only on rising or falling edges. This is controlled by the Interrupt Mode Registers
(IMRn). Interrupts on a pin can be enabled regardless of the GPIO pin being controlled by the
GPIO or assigned to a peripheral function.
An interrupt can be generated on each GPIO pin. These interrupt generators are further grouped
into groups of eight and connected to the interrupt controller. An interrupt request from any of the
GPIO pin generators in the group will result in an interrupt request from that group to the inter-
rupt controller if the corresponding bit for the GPIO pin in the IER is set. By grouping interrupt
generators into groups of eight, four different interrupt handlers can be installed for each GPIO
port.
The Interrupt Flag Register (IFR) can be read by software to determine which pin(s) caused the
interrupt. The interrupt flag must be manually cleared by writing a zero to the corresponding bit
in IFR.
GPIO interrupts will only be generated when CLK_GPIO is enabled.
Input glitch filters can be enabled on each GPIO pin. When the glitch filter is enabled, a glitch
with duration of less than 1 CLK_GPIO cycle is automatically rejected, while a pulse with dura-
tion of 2 CLK_GPIO cycles or more is accepted. For pulse durations between 1 and 2
CLK_GPIO cycles, the pulse may or may not be taken into account, depending on the precise
timing of its occurrence. Thus for a pulse to be guaranteed visible it must exceed 2 CLK_GPIO
cycles, whereas for a glitch to be reliably filtered out, its duration must not exceed 1 CLK_GPIO
cycle. The filter introduces 2 clock cycles latency.
The glitch filters are controlled by the Glitch Filter Enable Register (GFER). When a bit in GFER
is one, the glitch filter on the corresponding pin is enabled. The glitch filter affects only interrupt
inputs. Inputs to peripherals or the value read through PVR are not affected by the glitch filters.

disabled. For the pulse to be registered, it must be sampled at the rising edge of the clock. In this
example, this is not the case for the first pulse. The second pulse is sampled on a rising edge
and will trigger an interrupt request.

enabled. For the pulse to be registered, it must be sampled on two subsequent rising edges. In
the example, the first pulse is rejected while the second pulse is accepted and causes an inter-
rupt request.
