BIT FIELD TYPE DEFAULT DESCRIPTION

7-0 RTP_INPUT[7:0] R/W 0

This field is the entry point for real-time playback (RTP) data. The

DRV2605L playback engine drives the RTP_INPUT[7:0] value to the load

when MODE[2:0] = 5 (RTP mode). The RTP_INPUT[7:0] value can be

updated in real-time by the host controller to create haptic waveforms. The

RTP_INPUT[7:0] value is interpreted as signed by default, but can be set to

unsigned by the DATA_FORMAT_RTP bit in register 0x1D. When the

haptic waveform is complete, the user can idle the device by setting

MODE[2:0] = 0, or alternatively by setting STANDBY = 1.

7-5 Reserved

4 HI_Z R/W 0

This bit sets the output driver into a true high-impedance state. The device

must be enabled to go into the high-impedance state. When in hardware

shutdown or standby mode, the output drivers have 15 kΩ to ground. When

the HI_Z bit is asserted, the hi-Z functionality takes effect immediately, even

if a transaction is taking place.

3 Reserved

2-0 LIBRARY_SEL R/W 1

Waveform library selection value. This bit determines which library the

playback engine selects when the GO bit is set. For additional details on the

ERM libraries see the Table 1 section.
