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. <gpio-num> 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.
