The default register setting after the device power−up is
the following.
• Register bit CHIP_EN high in standby mode. OSC is
internally set for a clock cycle of 1 ms duration.
• Haptic mode default: Forward time = 20 ms, Coast time
= 0 ms, Reverse time = 10 ms, Recovery time = 32 ms.
• Haptic mode default: LDO output set to VIN. Vibrate
mode default LDO output set to 2.5 V.
