The SPI clock frequency is limited to SYSCLK/2 in mas-
ter mode and SYSCLK/8 in slave mode. Figure 10
shows the functional diagram of the SPI port. Figures 1
and 2 illustrate the timing parameters listed in the
Electrical Characteristics table.
General-Purpose Digital I/Os
The MAXQ7670A provides seven general-purpose digi-
tal I/Os (GPIOs). Some of the GPIOs include an addi-
tional special function (SF), such as a timer
input/output. For example, the state of P0.6/T0 is pro-
grammable to depend on timer channel 0 logic. When
used as a port, each I/O is configurable for high-imped-
ance, weak pullup to DVDDIO or pulldown to GNDIO.
At power-up, each GPIO is configured as an input with
a pullup to DVDDIO. In addition, each GPIO can be
programmed to cause an interrupt (on falling or rising
edges). In stop mode, use any interrupt to wake-up the
device.
The port direction (PD) register determines the
input/output direction of each I/O. The port output (PO)
register contains the current state of the logic output
buffers. When an I/O is configured as an output, writing
to the PO register controls the output logic state.
Reading the PO register shows the current state of the
output buffers, independent of the data direction. The
