• Manufacturer Part Number: MC1151A
• Description: (MC1x51A) Advanced Step Motor Control Chipset
• Manufacturer: PMD

RESET
Data/direction:
Encoding:
Axis acted on:
Available on:
Double buffered:
RESET resets the entire chip set. This command performs the same
sequence as a hardware reset. At the end of this operation the chip set
will be in the default or powerup condition, defined as follows:
GET_VRSN
Data/direction:
Encoding:
Axis acted on:
Available on:
Double buffered:
GET_VRSN returns various information on the chipset part number and
software version. The encoding is as follows:
Bit #
0-2
3-4
5-7
8-10
11-13
14-15
For example, the returned version code for the MC1401 (version 1.0
software) is 5908 (hex), the returned version code for the MC1201-P

(version 1.0 software) is 4928, and the returned version code for the
MC1451A (version 2.1 software) is 5c11.
GET_TIME
Data/direction:
Encoding:
Axis acted on:
Available on:
Double buffered:
GET_TIME returns the current system time, expressed as the number
of cycles since chip set power on.The chip set clock starts at 0 after a
power on or reset and will count indefinitely, wrapping from a value of
4,294,967,296 to 0. The returned value is a 32 bit number with units of
cycles.
Return current chip set time.
