6.3.1.12.106 Pad Configuration Register 216 (SIU_PCR216)
The SIU_PCR216 register controls the pin function, direction, and static electrical attributes of the
AN[13]_MA[1]_SDO pin.
Figure 6-118. AN[13]_MA[1]_SDO Pad Configuration Register (SIU_PCR216)
Refer to Table 6-16 for bit field definitions. The PA field for PCR216 is given in Table 6-42.
6.3.1.12.107 Pad Configuration Register 217 (SIU_PCR217)
The SIU_PCR217 register controls the pin function, direction, and static electrical attributes of the
AN[14]_MA[2]_SDI pin.
Figure 6-119. AN[14]_MA[2]_SDI Pad Configuration Register (SIU_PCR217)
Refer to Table 6-16 for bit field definitions. The PA field for PCR217 is given in Table 6-43.
