Description
Short To Battery Threshold
00 = 0.7 V
01 = 0.9 V
10 = 1.1 V
11 = 1.3 V
Short to Battery Retry Time
Retry after 4 * SB_RETRY * PWM periods
Retry Period = ^{4 ∗ SB_Retryx}
f _PWM
If the SB_RETRY field is programmed to the value 0, the short to battery retry period is identical to the programmed
the PWM period as programmed in SPI message #1.
