Table 81. GPIO n Direction Register
Register Description
The GPIO n Direction register controls the direction of the GPIO
data pins (input/output). The GPIO 0 Direction register controls
GPIO15 to GPIO0 while the GPIO 1 Direction register controls
GPIO31 to GPIO16.
Direction Select (Bits [15:0])
The Direction Select field[15:0] configures the corresponding
GPIO15–0 or GPIO31–16 pins as either input or output. When
any bit of this register is set to ‘1’, the corresponding GPIO data
pin becomes an output. When any bit of this register is set to ‘0’,
the corresponding GPIO data pin becomes an input.
IDE Mode Register [0xC048] [R/ W]
Table 83. IDE Mode Register
Register Description
The IDE Mode register allows the selection of IDE PIO Modes 0,
1, 2, 3, or 4. The default setting is zero which means IDE PIO
Mode 0.

IDE Registers
In addition to the standard IDE PIO Port registers, there are four
registers dedicated to IDE operation. These registers are
covered in this section and summarized in
Table 82. IDE Registers
Mode Select (Bits [2:0])
The Mode Select field sets PIO Mode 0 to 4 in IDE mode. Refer
