6 / 13 page ISL29027 6 FN7815.0 February 7, 2011 Register Descriptions TABLE 2. REGISTER 0x00 (RESERVED) BIT # ACCESS DEFAULT NAME FUNCTION/OPERATION 7:0 RO (n/a) (n/a) Reserved - no need to read or write TABLE 3. REGISTER 0x01 (CONFIGURE) - PROX CONFIGURATION BIT # ACCESS DEFAULT NAME FUNCTION/OPERATION 7RW 0x00 PROX_EN (Prox Enable) When = 0, proximity sensing is disabled When = 1, continuous proximity sensing is enabled. Prox data will be ready 0.54ms after this bit is set high 6:4 RW 0x00 PROX_SLP (Prox Sleep) For bits 6:4 = (see the following) 111; sleep time between prox IR LED pulses is 0.0ms (run continuously) 110; sleep time between prox IR LED pulses is 12.5ms 101; sleep time between prox IR LED pulses is 50ms 100; sleep time between prox IR LED pulses is 75ms 011; sleep time between prox IR LED pulses is 100ms 010; sleep time between prox IR LED pulses is 200ms 001; sleep time between prox IR LED pulses is 400ms 000; sleep time between prox IR LED pulses is 800ms 3RW 0x00 PROX_DR (Prox Drive) When = 0, IRDR behaves as a pulsed 110mA current sink When = 1, IRDR behaves as a pulsed 220mA current sink 2RW 0x00 Unused (Write 0) Unused register bit (write 0) 1RW 0x00 Unused (Write 0) Unused register bit (write 0) 0RW 0x00 Unused (Write 0) Unused register bit (write 0) TABLE 4. REGISTER 0x02 (INTERRUPT) - PROX INTERRUPT CONTROL BIT # ACCESS DEFAULT BIT NAME FUNCTION/OPERATION 7FLAG 0x00 PROX_FLAG (Prox Flag) When = 0, no Prox interrupt event has occurred since power-on or last “clear” When = 1, a Prox interrupt event occurred. Clearable by writing “0” 6:5 RW 0x00 PROX_PRST (Prox Persist) For bits 6:5 = (see the following) 00; set PROX_FLAG if 1 conversion result trips the threshold value 01; set PROX_FLAG if 4 conversion results trip the threshold value 10; set PROX_FLAG if 8 conversion results trip the threshold value 11; set PROX_FLAG if 16 conversion results trip the threshold value 4RW 0x00 Unused (Write 0) Unused register bit - write 0 3RW 0x00 Unused (Write 0) Unused register bit - write 0 2:1 RW 0x00 Unused (Write 0) Unused register bit - write 0 0RW 0x00 Unused (Write 0) Unused register bit - write 0 TABLE 5. REGISTER 0x03 (PROX_LT) - INTERRUPT LOW THRESHOLD FOR PROXIMITY SENSOR BIT # ACCESS DEFAULT BIT NAME FUNCTION/OPERATION 7:0 RW 0x00 PROX_LT (Prox Threshold) 8-bit interrupt low threshold for proximity sensing |
