Conditions: CFG_IOP = 0
P3 is General-Purpose Discrete I/O
P3 is BiSS Command Controlled Output

MCL is General-Purpose Discrete I/O
MCL is BiSS Command Controlled Output
If ENCMD3 = 1, a BiSS command with CMD = 3 initi-
ates a position preset sequence. Refer to POSITION
OFFSET and PRESET (Zero Position) on page 55 for
more information.
BiSS access to certain registers in the iC-MHM RAM
and its external EEPROM can be restricted using pa-
rameters REGPROT and INSPROT.

P3 and MCL
An addressed BiSS command with CMD = 2 sets pin 7
high. A BiSS broadcast command with CMD = 2 resets
pin 7 low. Refer to SERIAL INTERFACE: BiSS MODE
on page 37 for more information.
A BiSS command with CMD = 3 can be configured to
initiate a position preset sequence using parameter
ENCMD3.
