SYSTEM TOOLS
Table 22 provides an overview of the control registers that provide
support for the following system level functions: global commands,
I/O control, status/error flags, device identification, MEMS self-
test, and flash memory management.

GLOBAL COMMANDS
The GLOB_CMD register provides an array of single-write
commands for convenience. Setting the assigned bit in Table 23
to 1 activates each function. When the function completes, the
bit restores itself to 0. For example, clear the capture buffers by
setting GLOB_CMD[8] = 1 (DIN = 0xBF01). All of the commands
in the GLOB_CMD register require the power supply to be within
normal limits for the execution times listed in Table 23. Avoid
communicating with the SPI interface during these execution
times because it interrupts the process and causes data loss or
corruption.

General-Purpose I/O
DIO1, DIO2, DIO3, and DIO4 are configurable, general-purpose
I/O lines that serve multiple purposes according to the following
control register priority: MSC_CTRL, ALM_CTRL, and
GPIO_CTRL. For example, set GPIO_CTRL = 0x080C (DIN =
0xB308, and then 0xB20C) to configure DIO1 and DIO2 as inputs
and DIO3 and DIO4 as outputs, with DIO3 set low and DIO4
set high. In this configuration, read GPIO_CTRL (DIN = 0x3200).
The digital state of DIO1 and DIO2 is in GPIO_CTRL[9:8].
This indicates the typical duration of time between the command write and
the device returning to normal operation.

Data Ready I/O Indicator
The factory default sets DIO1 as a positive data ready indicator
signal. In this configuration, the signal pulses high when all of
the output data registers have fresh data from the same sample
period. The MSC_CTRL[2:0] bits provide configuration options
for changing the default. For example, set MSC_CTRL[2:0] = 100
(DIN = 0xB404) to change the polarity of the data ready signal
on DIO1 for interrupt inputs that require negative logic inputs
for activation. See Figure 4 for an example of the data-ready timing.
