Table 21 GPIO General Commands

Command

Description

GPIO #1 is normal

GPIO #2 is special

GPIO #3 is special

GPIO #4 is special

GPIO #5 is special

GPIO #6 is special

GPIO #7 is special

GPIO #8 is special

SET GPIO SPECM <bit-mask>

Sets all special function control bits. <bit-mask> 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 enables the special function on the

corresponding GPIO signal, a value of 0 disables the special

function. For example, a hex value of 80 sets GPIO8 for a

special function, all other GPIO signals for general use.

NOTE: The special function bit configuration is not changed

by a configuration reset to default. This command has no

effect on GPIO 1 and 2, which do not have special functions.

SHOW GPIO SPECM

Shows GPIO special functions control bits as a mask value.

Example:

Local> set gpio specm 80

Local> show gpio specm

GPIO special function mask=80

1 2 ... 56 57 58 59 60 61 62 63 64 65 66 ... 103 104
