Haptic Output Duration (Phase 1)

Selects the duration of Phase 1 in one-

shot mode.

000h = 0ms

001h = 0.625ms

002h = 1.25ms

… (0.625ms steps)

1FFh = 319.375ms

Haptic Output Level (Phase 2)

Selects the signal intensity in Continuous

mode or Phase 2 of one-shot mode.

Coded as 2’s complement.

Range is +/- Full Scale (FS).

For ERM actuator, this selects the DC

signal level for the haptic output.

For LRA actuator, this selects the AC peak

amplitude; Negative values correspond to

a 180 degree phase shift.

Haptic Output Level (Phase 3)

Selects the signal intensity of Phase 3 in

one-shot mode.

Coded as 2’s complement.

Range is +/- Full Scale (FS).

For ERM actuator, this selects the DC

signal level for the haptic output.

For LRA actuator, this selects the AC peak

Table 20 Haptic Signal Generator Control

PWM GENERATOR

The CS47L85 incorporates two Pulse Width Modulation (PWM) signal generators as illustrated in Figure 36. The duty cycle

of each PWM signal can be modulated by an audio source, or can be set to a fixed value using a control register setting.

A 4-input mixer is associated with each PWM generator. The 4 input sources are selectable in each case, and independent

volume control is provided for each path.

The PWM signal generator

s can be output directly on a GPIO pin. See “General Purpose Input / Output” to configure a GPIO

pin for this function.
