SLVS551 – DECEMBER 2004
Bit 3-Bit 2 - The function of the LDO1 enable and LDO1 OFF / nSLP bits is shown in the following table. See the
power-on sequencing section for details of low-power mode. Note that programming LDO1 to a higher voltage
may force a system power-on reset if the increase is in the 10% or greater range.

Bit 1-Bit 0 - LDO1<1:0>: The LDO1 output voltage is per default set externally. If so desired, this can be changed
via the serial interface.

The MASK3 register must be considered when any of the GPIO pins are programmed as inputs.
Bit 7-Bit 4 - Edge trigger GPIO<4:1>: determine whether the respective GPIO generates an interrupt at a rising or
a falling edge.
0 = falling edge triggered.
1 = rising edge triggered.
Bit 3-Bit 0 - Mask GPIO<4:1>: can be used to mask the corresponding interrupt. Default is unmasked (mask
GPIOx = 0).

The DEFGPIO register is used to define the GPIO pins to be either input or output.
Bit 7-Bit 4 - IO<4:1>:
0 = sets the corresponding GPIO to be an input.
1 = sets the corresponding GPIO to be an output.
Bit 3-Bit 0 - Value GPIO<4:1>: If a GPIO is programmed to be an output, then the signal output is determined by
the corresponding bit. The output circuit for each GPIO is an open-drain NMOS requiring an external pullup
resistor.
1 = activates the relevant NMOS, hence forcing a logic low signal at the GPIO pin.
0 = turns the open-drain transistor OFF, hence the voltage at the GPIO pin is determined by the voltage to
which the pullup resistor is connected.
If a particular GPIO is programmed to be an input, then the contents of the relevant bit in B3-0 is defined by the
logic level at the GPIO pin. A logic low forces a 0 and a logic high forces a 1. If a GPIO is programmed to be an
input, then any attempt to write to the relevant bit in B3-0 is ignored.
