C
Address 37: Main clock divider
Table 27 Clock divider: CLK_DIV; note 1
Note
1. CD selects the main clock division factor. The CLKIN frequency (pin 6) divided by this factor gives the IC’s operating
Table 28 Clock division factor
S
Address 38: Stripe detector nominal frequency
Table 29 Qualification threshold: STRIPE_F; note 1
Note
1. SF is an unsigned 5-bit value used to determine the detection threshold for the stripe detector. The nominal detection
