Ｐ２Ｍ ２
“P2M” is the parameter setting the logical level of a synchronous pulse and pulse width. In addition, it can set the synchronous
action disabling when an error occurs, the mode setting for driving by external signals, the logical level of split pulse output and
with or without starting pulse.

D7 ERRDE
Setting for whether the enabling status of synchronous action SYNC3~0 is disabled or not when an error
occurs (RR0/D7
～
4
：
n-ERR = 1).
0: not disable at the error, 1: disable at the error
When this bit is set to 1, and when n-ERR bit of RR0 register becomes 1, synchronous action SYNC3~0 is
all disabled immediately.
When n-ERR bit of RR0 register is 1, synchronous action SYNC3~0 cannot be enabled again. Clear the
error bit by such as the error/finishing status clear command (79h) and then set the synchronous action
enable setting.
Error status and enable / disable setting of synchronous action SYNC3~0 can be checked by Page 1 of RR3
register.
