Refer to Table 6-19 for bit field definitions. Table 6-112 lists the PA fields for
EMIOS[23]_ETPUB[7]_GPIO[202].
6.3.1.113 Pad Configuration Registers 203–204 (SIU_PCR203–SIU_PCR204)
The SIU_PCR203–SIU_PCR204 registers control the function, direction, and electrical attributes of
EMIOS[14:15]_GPIO[203:204]. Only the output functions of EMIOS[14:15] are connected. These
signals are referred to as GPIO[203:204] because other balls are named EMIOS[14:15]. The primary
function is EMIOS, however the default out of reset is GPIO. These signals are not affected by WKPCFG.

Refer to Table 6-19 for bit field definitions. Table 6-113 lists the PA fields for
EMIOS[14:15]_GPIO[203:204].
6.3.1.114 Pad Configuration Register 205 (SIU_PCR205)
The SIU_PCR205 register controls the direction and electrical attributes of the GPIO[205] pin. This
register is separate from the PCRs for GPIO[206:207] since GPIO[205] is a medium pad type with slew

When configured as EMIOS[14:15] the OBE bit has no effect. When GPIO[203:204] is configured as output, set the OBE bit
to 1.

When the pad is configured as an output, set the IBE bit to 1 to show the pin state in the GPDI register. Clear the IBE bit to 0
to reduce power consumption. When configured as GPDI, set the IBE bit to 1.
