SC9OFF_HB [6:0] SC9 off time for the even numbered pulses when heartbeat mode for this channel is enabled. When the
SC9OFF_HB time is disabled, SC9 goes immediately from the even numbered on time to the odd numbered on
time. When the SC off time is set to any other value, the ISC turns off for the off time (per the following listed
times) and then turns on according to the SCON9_HB setting.

A disabled setting leaves the LED on. This is useful for setting up a blink sequence that runs once and then stays on.
2
Setting SCxOFF_HB to 0 seconds is not recommended if the SCFO_HB fade-out time is also set to 0 seconds.
3
Setting SCxOFF to off causes the LED to be held off indefinitely. This is useful for setting up a blink sequence that runs once and then goes to off.
