PRODUCTION DATA.
| 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
| ACQ | PROG | HiZ | AVG[1:0] | Not used | Not used | VCOM[8] | |
| R/W-0h | R/W-0h | R/W-0h | R/W-0h | R/W-1h | R/W-0h | R/W-0h | |
| LEGEND: R/W = Read/Write; R = Read only; -n = value after reset |
| Bit | Field | Type | Reset | Description |
|---|---|---|---|---|
| 7 | ACQ | R/W | 0h | Kick-back voltage acquisition bit
0h = No effect 1h = Starts kick-back voltage measurement routine NOTE: After measurement is complete bit is cleared automatically and measurement result is reflected in VCOM[8:0] bits. |
| 6 | PROG | R/W | 0h | VCOM programming bit
0h = No effect 1h = VCOM[8:0] value is committed to nonvolatile memory and becomes new power-up default NOTE: After programming bit is cleared automatically and TPS65185x will enter STANDBY mode. |
| 5 | HiZ | R/W | 0h | VCOM HiZ bit
1h = VCOM pin is placed into hi-impedance state to allow VCOM measurement 0h = VCOM amplifier is connected to VCOM pin |
| 4-3 | AVG | R/W | 0h | Number of acquisitions that is averaged to a single kick-back voltage measurement
0h = 1x 1h = 2x 2h = 4x 3h = 8x NOTE: When the ACQ bit is set, the state machine repeat the A/D conversion of the kick-back voltage AVD[1:0] times and returns a single, averaged, value to VCOM[8:0] |
| 2 | Not used | R/W | 1h | N/A |
| 1 | Not used | R/W | 0h | N/A |
| 0 | VCOM | R/W | 0h | VCOM voltage adjustment
VCOM = VCOM[8:0] x –10 mV in the range from 0 mV to –5.110 V 0h = –0 mV 1h = –10 mV 2h = –20 mV ... 7Dh = –1250 mV ... 1FEh = –5100 mV 1FFh = –5110 mV |
