GPIO2→FFFF7000h)
In all cases, the bits of these correspond to a single GPIO pin: bit 0 corresponds to GPIO_0[0], bit 1 to
GPIO_0[1], etc. Unless otherwise specified, the default state for each bit in these registers is ‘0’.

Description
Enable (GPIO_EN): When set, the secondary (GPIO) function is enabled. This register can be
written directly or by using GPIO_EN_SET and GPIO_EN_CLR.
Enable Set (GPIO_EN_SET): Writing a ‘1’ sets GPIO_EN.
Enable Clear (GPIO_EN_CLR): Writing a ‘1’ clears GPIO_EN.
Output Enable (GPIO_OE): When ‘0’, disable output. When ‘1’, enable output. This can be
written directly or by using GPIO_OE_SET and GPIO_OE_CLR.
Output Enable Set (GPIO_OE_SET): Writing a ‘1’ sets GPIO_OE.
Output Enable Clear (GPIO_OE_CLR): Writing a ‘1’ clears the GPIO_OE.
Output (GPIO_OUT): When ‘0’, drive ‘0’ on GPIO output. When ‘1’, drive ‘1’ on GPIO output.
This can be written directly or by using GPIO_OUT_SET and GPIO_OUT_CLR.
GPIO_EN must be active.
Output Set (GPIO_OUT_SEL): Writing a ‘1’ sets GPIO_OUT.
Output Clear (GPIO_OUT_CLR): Writing a ‘1’ clears GPIO_OUT.
Input (GPIO_IN): ‘0’ means pin is a ‘0’. ‘1’ means pin is a ‘1’. Always represents the state of
the pin, even if GPIO_EN is inactive. Reset value is undefined.
Interrupt Mode (GPIO_IMOD): ‘0’ = level triggered. ‘1’ = edge triggered.
Polarity (GPIO_IPOL): ‘0’ means interrupts latched on “falling” condition. ‘1’ means interrupts
A/B are latched on a “rising” condition
Interrupt Channel Select (GPIO_ISEL): When set, use interrupt channel B. When cleared,
use interrupt channel A.
Interrupt Enable (GPIO_IEN):
Disabling this bit does not mask an existing pending interrupt from driving an interrupt into the
INTC.
Interrupt Enable Set (GPIO_IEN_SET): Writing a ‘1’ sets GPIO_IEN.
Interrupt Enable Clear (GPIO_IEN_CLR): Writing a ‘1’ clears GPIO_IEN.
Interrupt Channel-A Status (GPIO_IAST):
associated with this pin. Use GPIO_ICLR to clear.
Interrupt Channel-B Status (GPIO_IBST):
associated with this pin. Use GPIO_ICLR to clear.
Interrupt Clear (GPIO_ICLR): When written to ’1’, clears Interrupt Pending Flop and Edge
Detector Flops. Clearing Interrupt Pending Flop clears the corresponding bit in GPIO_IAST and
GPIO_IBST.
Wake (GPIO_WKEN): When set, enables PMU wake for pin on an edge condition.
Wake Enable Set (GPIO_WKEN_SET): Writing a ‘1’ sets GPIO_WKEN.
Wake Enable Clear (GPIO_WKEN_CLR): Writing a ‘1’ clears GPIO_WKEN.
Open-Drain register (GPIO_OPEN_D): This only applies to GPIO0 [15:0]. When set, enables
open-drain mode.
GPIO0 default value: FF00FFFFh
GPIO1 default value: FFFFFFFFh
GPIO2 default value: 00000FFFh
When set, allows the Interrupt Pending Flop to be set.
When set, outstanding channel A interrupt
When set, outstanding channel B interrupt
