Disable setting
Each synchronous action set can be disabled by synchronous action disable setting command (91h~9Fh).
When the synchronous action set is disabled, the action is not invoked by when the activation factor is activated.
4 synchronous action sets are all disabled at reset.
4 synchronous action sets have each corresponding command code. Synchronous action set SYNC0 is 91h, SYNC1 is 92h,
SYNC2 is 94h and SYNC3 is 98h. These commands can be disabled in combination simultaneously as well as synchronous action
enable setting command. For more details of a combination of command codes, see table 2.6-7.
There are 3 occasions to change the state of a synchronous action to disable, “when synchronous action disable setting command
is written”, “when an error occurs by PIO signal setting 2
・
Other settings command (22h) when synchronous action disable setting
(D7
：
ERRDE) is set to enable”, and “after the synchronous action is activated when it is set once (disable the repeat setting)”.
Enable/disable of 4 synchronous action sets can be checked by D3
～
D0 bits (SYNC3~SYNC0) of RR3 register Page1.
