TMD2621 − Register Overview
PWTIME Register (Address 0xEC)
Figure 58:
PWTIME Register
The PWTIME is implemented using a down counter and starts
counting from very beginning of every proximity measurement
cycle including the initialization time. If enabled, PWTIME needs
to be programmed greater than proximity measurement time,
otherwise it's ignored.
PWTIME =Wait Cycles x2.779ms.
If PWLONG is enabled, then PWTIME =Wait Cycles x2.779ms x12.
Note that PWTIME is ignored if MODE_CFG (CFG3 (0xAB),
bit[6:5])=00b.
PDATA_L Register (Address 0xF4)

If APC is enabled, this register contains the low byte of
the 14-bit proximity data.
If APC is disabled, this register contains the upper 8
most significant bits of the 10-bit proximity data.
