Register Description
PIHTL Register (0x8A) Figure 19: PIHTL Register Addr:0x8A PIHTL Bit Bit Name Default Access Bit Description
This register contains the low byte of the 14-bit proximity HIGH threshold when APC is enabled. If APC 7:0 PIHTL 0x00 RW is disabled, this register contains the HIGH threshold which is an 8-bit value which is compared against the upper 8 bits of the 10-bit proximity value.
PIHTH Register (0x8B) Figure 20: PIHTH Register Addr:0x8B PIHTH Bit Bit Name Default Access Bit Description
7:6 Reserved 00 RW Reserved. Must be set to default value. This register contains the upper 6 bits of the 14-bit 5:0 PIHTH 0x00 RW proximity HIGH threshold when APC is enabled. If APC is disabled, this register is ignored. The contents of the PIHTH and PIHTL registers are combined and treated as a fourteen (14) bit threshold high value. If the value generated by the proximity ADC (PDATA) is above the PIHTL/H threshold and the PPERS value is reached, then the high proximity threshold is breached. When setting the 14-bit proximity threshold, PIHTL must be written first, immediately follow by PIHTH. Internally, the lower 8 bits are buffered until the upper 8 bits are written. As the upper 8 bits are written both the high and low bytes are simultaneously latched as a 14-bit value. If Automatic Pulse Control (APC) is disabled by setting bit 6 in CFG6 to 1, then the proximity data converts to a 10-bit value. PIHTL contains an 8-bit threshold which is compared against the upper 8 bits of the 10-bit value. PIHTH is ignored.
