SCO control for hostless gateway operation.
 0 – Normal
 1 – As early as possible
 2 – Leave SCO to be controlled by headset

Number of times this module has gone through a reset cycle. This
feature is enabled by S Reg 601.
Writing any value to this register initialises it to a certain value.

If this is 1, then on reset S Reg 600 value is incremented.

Set direction of digital I/O lines. This is a mask made up of 5 bits.
Setting a bit to 1 makes that I/O line an output. GPIO1 is bit 0, GPIO2
is bit 1, up to bit 8 for GPIO9.

Set to 1 to invert the logic of GPIO outputs. For example, ATS621=1
sets the output pin to low and vice versa.

Read/Write to all eight digital lines in one atomic step. The value is
returned as a four digit hexadecimal value with trailing 0s.

When GPIO1 is configured as an input, low to high transitions are
counted. There is no software debouncing. External RC circuit may
be required.
The counter wraps to 0 when it overflows beyond 65535.
S632
n/a
0..65535
When GPIO2 is configured as an input, low to high transitions are
counted. There is no software debouncing. External RC circuit may
be required.
The counter wraps to 0 when it overflows beyond 65535.
S641

0..65535
As per 631, but the action of reading the value resets the count to 0.
S642
n/a
0..65535
As per 632, but the action of reading the value resets the count to 0.
S701

0..65535
Read to Analogue Line 0, when reading value is returned in decimal.
