6.3.1.12.102 Pad Configuration Register 211–212 (SIU_PCR211–SIU_PCR212)
The SIU_PCR211–SIU_PCR212 registers control the pin function, direction, and static electrical
attributes of the BOOTCFG[0:1]_IRQ[2:3]_GPIO[211:212] pins.

Pad Configuration Register (SIU_PCR211–SIU_PCR212)
Refer to Table 6-16 for bit field definitions.
6.3.1.12.103 Pad Configuration Register 213 (SIU_PCR213)
The SIU_PCR213 register controls the pin function, direction, and static electrical attributes of the
WKPCFG_GPIO[213] pin.

The BOOTCFG function applies only during reset when the RSTCFG pin is asserted during reset. Set the PA field to 0b10 for
IRQ[2:3] and clear the PA field to 0b00 for GPIO[211:212].
OBE

When configured as IRQ, the OBE bit has no effect. When configured as GPO, set the OBE bit to 1.
IBE

3
When configured as IRQ or GPO, set the IBE bit to 1 to reflect the pin state in the corresponding GPDI register. Clear the IBE
to 0 to reduce power consumption. When configured as GPI, set the IBE bit to 1.
