VBUS Valid Flag (Bit 0)
The VBUS Valid Flag bit indicates whether OTG VBus is
greater than 4.4V. After turning on VBUS, firmware should wait
at least 10 µs before this reading this bit.
GPIO Registers
There are seven registers dedicated for GPIO operations. These seven registers are covered in this section and summarized in
Table
Table 29.GPIO Registers
GPIO Control Register [0xC006] [R/W]
Register Description
The GPIO Control register configures the GPIO pins for
various interface options. It also controls the polarity of the
GPIO interrupt on IRQ0 (GPIO24).
Write Protect Enable (Bit 15)
The Write Protect Enable bit enables or disables the GPIO
write protect. When Write Protect is enabled, the GPIO Mode
Select [15:8] bits are read-only until a chip reset.
1: Enable Write Protect
0: Disable Write Protect
SAS Enable (Bit 11)
The SAS Enable bit, when in SPI mode, reroutes the SPI port
SPI_nSSI pin to GPIO[15] rather then GPIO[9].
1: Reroute SPI_nss to GPIO[15]
0: Leave SPI_nss on GPIO[9]
