Real-Time Playback Input (Address: 0x02)

Bit 7 6 5 4 3 2 1 0

Function RTP_Input[7] RTP_Input[6] RTP_Input[5] RTP_Input[4] RTP_Input[3] RTP_Input[2] RTP_Input[1] RTP_Input[0]

Type R/W R/W R/W R/W R/W R/W R/W R/W

Default 0 0 0 0 0 0 0 0

RTP_Input[7:0] This is the entry point for Real-Time Playback (RTP) data. The DRV2605 playback engine will

drive the RTP_Input value to the load when Mode = 5 (RTP Mode). The RTP_Input value may

be updated on the fly by the host controller to create haptic waveforms. The RTP_Input value

is interpreted as signed by default, but may be set to unsigned by DataFormat_RTP. When the

haptic waveform is complete, the user may park the device by setting Mode = 0, or

alternatively by setting STANDBY = 1.

Library Selection (Address: 0x03)

Bit 7 6 5 4 3 2 1 0

Function HiZ LibrarySel[2] LibrarySel[1] LibrarySel[0]

Type R/W R/W R/W R/W

Default 0 0 0 0

HiZ HiZ 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 HiZ is asserted, it takes effect immediately,

even if a transaction is taking place.

LibrarySel[2:0] Waveform library selection value. This determines which library the playback engine goes to

when the GO bit is set.
