Description
SC4 off time. When the SC off time is disabled, the ISC remains on while enabled. When the SC off time is
set to any other value, then the ISC turns off for the off time (per the following listed times) and then
turns on according to the SCON setting.
00 = off time disabled
01 = 0.6 sec
10 = 1.2 sec
11 = 1.8 sec
SC3 off time. When the SC off time is disabled, the ISC remains on while enabled. When the SC off time is
set to any other value, then the ISC turns off for the off time (per the following listed times) and then
turns on according to the SCON setting.
00 = off time disabled
01 = 0.6 sec
10 = 1.2 sec
11 = 1.8 sec
