PSWITCH Pin Functions
11.4.3 Software Functions/Recovery Mode
When the PSWITCH pin voltage is pulled up to the minimum MID level (as specified in
Table
11-1) the lower HW_POWER_STS_PSWITCH bit is set. Software can poll this bit
and perform a function as desired by the product designer. Example functions include a
play/pause/power-down button, delay for startup, and so on.
When the PSWITCH pin is connected to VDDIO through a current limiting resistor, the
upper HW_POWER_STS_PSWITCH bit is also set. If this bit is set for more than five
seconds during ROM boot, the system executes the Freescale USB Firmware Recovery
function, as described in
Boot
Modes. If the product designer does not wish to use Freescale
USB Firmware Recovery, the product can be designed to not assert a voltage higher than
the maximum MID level (as specified in
Table
11-1) on the PSWITCH pin.
Refer to the Freescale i.MX28 reference schematics for example configurations of the
PSWITCH pin.
