Register Description
PCFG0 Register (0x8E) Figure 23: PCFG0 Register Addr : 0x8E PCFG0 Bit Bit Name Default Access Bit Description
This field sets the gain of the proximity IR sensor.
Value Gain
0 (00) 1x 2 7:6 PGAIN RW (10) 1 (01) 2x 2 (10) 4x 3 (11) 8x Maximum number of pulses in a single proximity cycle.
Value Maximum Number of Pulses
0 (00000) 1 15 5:0 PPULSE RW 1 (00001) 2 (001111) 2 (00010) 3 ... ... 63 (11111) 64 The PPULSE field sets the maximum number of IR VCSEL pulses that may occur in a proximity cycle. The proximity engine will automatically continue to add IR VCSEL pulses, up to the value set in PPULSE or if a near-saturation condition occurs if Automatic Pulse Control (APC) is enabled. The dynamic range of the sensor is automatically adjusted to detect distant targets as well as prevent saturation from close targets. This operation also reduces power consumption because proximity integration period is automatically shortened when a target is close to the sensor. If Automatic Pulse Control (APC) is disabled by setting bit 6 in CFG6 to 1, then PPULSE always determines the number of proximity pulses to be transmitted.
