SET GPIO DIRM

GPIO # = {1|2|3|4|5|6|7|8}

Sets all direction control bits, where is an 8 bit
mask expressed as 2 hex digits. This value should be in the
range 00-FF. The mask is encoded as follows:

7 6 5 4 3 2 1 0
GPIO8 GPIO7 GPIO6 GPIO5 GPIO4 GPIO3 GPIO2 GPIO1


A value of 1 sets the corresponding GPIO line to be an
output. A value of 0 sets the GPIO line to be an input. For
example, a hex value of 80 sets GPIO8 as an output, all
other GPIO signals are input.

NOTE: The direction bit configuration is not changed by a
configuration reset to default.

SHOW GPIO DIRM

Shows all direction control bits

Example:

Local> set gpio dirm 01

Local> show gpio dirm

GPIO direction mask=01

SET GPIO SPECIAL [EN | DIS]

Sets a single special function control bit. This command
enables or disables the special function of the GPIO signal
specified. must be in the range of 1-8. The
special functions are as follows:

GPIO_1

(no special function)

GPIO_2

(SPI CS for LCD display)

GPIO_3

TSPICS (enables SPI temperature)

GPIO_4

DTR0 (Serial Port 1 DTR output)

GPIO_5

DSR0 (Serial Port 1 DSR input)

GPIO_6

DCD0 (Serial Port 1 DCD input)

GPIO_7

GRN (network status LED)

GPIO_8

YEL (network status LED)


NOTE: The special function bit configuration is not changed
by a configuration reset to default.

SHOW GPIO SPECIAL

Shows the current setting of the GPIO special function
configuration.
