6.3.1.123 Pad Configuration Register 216 (SIU_PCR216)
The SIU_PCR216 register controls the function, direction, and electrical attributes of
AN[13]_MA[1]_SDO.
Figure 6-124. AN[13]_MA[1]_SDO Pad Configuration Register (SIU_PCR216)
Refer to Table 6-19 for bit field definitions. Table 6-120 lists the PA fields for AN[13]_MA[1]_SDO.
6.3.1.124 Pad Configuration Register 217 (SIU_PCR217)
The SIU_PCR217 register controls the pin function, direction, and electrical attributes of
AN[14]_MA[2]_SDI.
Figure 6-125. AN[14]_MA[2]_SDI Pad Configuration Register (SIU_PCR217)
Refer to Table 6-19 for bit field definitions. Table 6-121 lists the PA fields for AN[14]_MA[2]_SDI.
