Initial Pulse
Width Enable
If '1', enables the Initial Pulse Width register values at startup.
If '0', the default value of 0 will be used.

If '1', enables the Transmit Delay and Transmit Pacing values.
If '0', the default values of 600uS and 70uS will be used.

Enable
If '1', enables execution of the startup string when power is applied to the SSC-32.
If '0', the startup string will not be executed.

Description
Examples
Register write:
R <r> = <n> <cr>
r = reg number, 0-255
n = value
Programs the value of a register.
Spaces are optional around the
register number and value.
R0=1023 <cr>
R32 = -50 <cr>
Register read:
R <r> <cr>
r = reg number, 0-255
Displays the value of a register,
followed by a carriage return. The
displayed value is in ASCII format,
and is terminated with a carriage
return.
R0 <cr>
result: 1023<cr>
R32 <cr>
result: -50<cr>
Set to defaults:
RDFLT <cr>
none
Sets all of the registers to their
default values. When the command
is complete the SSC-32 will
transmit the string OK<cr>.
RDFLT <cr>
result: OK<cr>
The RDFLT command may take over a second to execute. It should not be invoked while a
timed move or sequence player is active. No register writes should be performed until the
RDFLT is complete (as indicated by the 'ok' response).
If multiple R= commands are being sent by software, it is recommended that the software read
the value of each register after it is written. This will ensure that each register write has
completed before the next is started.
