6.3.1.12.104 Pad Configuration Register 214 (SIU_PCR214)
The SIU_PCR214 register controls the enabling/disabling and drive strength of the ENGCLK pin. The
ENGCLK pin is enabled and disabled by setting and clearing the OBE bit. The ENGCLK pin is enabled
during reset.

Refer to Table 6-16 for bit field definitions.
6.3.1.12.105 Pad Configuration Register 215 (SIU_PCR215)
The SIU_PCR215 register controls the pin function, direction, and static electrical attributes of the
AN[12]_MA[0]_SDS pin.
