!DIOCFG
Supporting chipsets:
• MDM6200
• MDM6270 (min f/w rev:
S2.0)
• MSM6290 (min f/w rev:
K1_1_1_3ap)
• QSC6270 (min f/w rev:
S2.0)
Note: This command is not
password-protected.
Configure DIO channels
Configure specific GPIOs for DIO (digital I/O) operation.
• If a DIO channel is disabled, the GPIO maintains its default functionality.
• After a channel is configured and enabled, it can be used for input or output (as
appropriate) using !DIO. See the tables below for channel configuration details.
• Input DIO channels—Choice to register level change notifications associated with
the corresponding DIO channels is specified as part of the configuration.
• Output DIO channels—Initial value to write to the DIO channel is specified as part of
the configuration.
MSM6290-based devices
Input channels can be configured for pull-up (P-Up) or pull-down (P-Dn) operation—
some restrictions apply to GPIOs connected to external resistors.
