• Manufacturer Part Number: cs5954am
• Description: Usb Controller For Nand Flash
• Manufacturer: Cypress Semiconductor Corporation.

5.1.1
This register controls the I/O direction of the GPIO data pins from GPIO15 to GPIO0. When any bit of this register set to one, the
corresponding GPIO data pin becomes an output pin. When any bit of this register is set to zero, the corresponding GPIO data
pin becomes an input pin.
5.1.2
This register controls the I/O direction of the GPIO data pins from GPIO31 to GPIO16. When any bit of this register set to one,
the corresponding GPIO data pin becomes an output pin. When any bit of this register is set to zero, the corresponding GPIO
data pin becomes an input pin.
5.1.3
This register controls the output data of the GPIO data pins from GPIO15 to GPIO0.
5.1.4
This register controls the output data of the GPIO data pins from GPIO31 to GPIO16.
5.1.5
This register reads the input data of the GPIO data pins from GPIO15 to GPIO0.
5.1.6
This register reads the input data of the GPIO data pins from GPIO31 to GPIO16.
Note:
Document #: 38-08025 Rev. **
25. A Read of this register reads back the last data written, not the data on pins configured as input (see below).
