13. GPIO Control Commands
107
Sets the special function for all 11 GPIO signals with a bitmask value.
SET GPIO SPECM <bit-mask>
<bit-mask> is an 11 bit mask expressed as 3 hex digits.
The value range must be 000-7FF.
The following table shows the definition of each bit for <bit-mask>.

When 1 is given for each bit of <bit-mask>, the special function of GPIO signals is enabled,
and when 0 is given, it is disabled.
For example, when 080 (hex) is entered for <bit-mask>, the special function of GPIO7 is
enabled, and the special function of other signals is disabled (they can be used for general
purpose).
13-7. SET GPIO SPECM
Shows the special function setting of GPIO signals as a bitmask value.
SH GPIO SPECM
Sample output:
Local> SH GPIO SPECM
GPIO special function mask = 03
13-8. SH GPIO SPECM
• This setting will remain even after the configuration is initialized.
