GPIO Status Register (EMC2103-2 Only)
The GPIO Status Register indicates which GPIO has changed states to cause the ALERT pin to be
asserted. This register is cleared when it is read. The bits in this register are set whenever the
corresponding GPIO changes states regardless if the ALERT pins are asserted. Once a bit is set, it
will remain set until read.
If any bit in this register is set, then the GPIO status bit will be set.
Bit 1 - GPIO2_STS - Indicates that the GPIO2 pin has changed states from a ‘0’ to a ‘1’ or a ‘1’ to a
‘0’ (when configured as a GPIO input).
Bit 0 - GPIO1_STS - Indicates that the GPIO1 pin has changed states from a ‘0’ to a ‘1’ or a ‘1’ to a
‘0’ (when configured as a GPIO input).
6.40
Software Lock Register
The Software Lock Register controls the software locking of critical registers. This register is software
locked.
Bit 0 - LOCK - this bit acts on all registers that are designated SWL. When this bit is set, the locked
registers become read only and cannot be updated.
‘0’ (default) - all SWL registers can be updated normally.
‘1’ - all SWL registers cannot be updated and a hard-reset is required to unlock them.
