Refer to Table 6-19 for bit field definitions. Table 6-145 lists the PA fields for CAL_TS.
6.3.1.158 Pad Configuration Register 299 (SIU_PCR299)
The SIU_PCR299 register controls the function, direction, and electrical attributes of
CAL_CS[1]_CAL_ADDR[9].
Figure 6-158. CAL_CS[1]_CAL_ADDR[9] Pad Configuration Registers (SIU_PCR299)
Refer to Table 6-19 for bit field definitions. Table 6-146 lists the PA fields for
CAL_CS[1]_CAL_ADDR[9].
6.3.1.159 GPIO Pin Data Output Registers 0–213 (SIU_GPDO n )
The 8-bit SIU_GPDO n registers defined in Figure 6-159 each specify the output data for the function
assigned to the GPIO[ n ] pin. The n notation in the 214 SIU_GPDO n register names relate to the [ n ] in
GPIO[ n ] signal name. For example, SIU_GPDO0 contains the PDO0 bit for CS[0]_GPIO[0]; and
SIU_GPDO213 contains the PDO213 bit for WKPCFG_GPIO[213]. The address for a GPDO pin is the
GPIO number plus an offset of SI 0x0600.
Software writes to the SIU_GPDO n registers to drive data out on the external pin. Each register drives one
external pin, which allows independent control of the pin. Writes to the SIU_GPDO n registers have no
effect if an input function is assigned to the pin by the pad configuration register.
If the direction of a GPIO signal changes from input to output, the SIU_GPDO n register value is
automatically driven out to the external pin without a software update.
