MSB (RXHIGHh): 36 = 24h
LSB (RXHIGHl): 37 = 25h
Each LSB of RXHIGHh represents 25.6µW and each ach LSB of RXHIGHl represents 0.1µW.. The value in this register is
uncalibrated. The sixteen bits threshold value (RXHIGHh;RXHIGHl) is compared, bit to bit, to the sixteen bits value of the RX
power reading (RXOPh:RXOPl). Warning bit Wx is set if Reading > Threshold.

This register is provided for compliance with SFF-8472. It is implemented as general-purpose non-volatile memory. Read/write
access is possible whenever a valid OEM password has been entered. CHKSUM is read-only in USER mode.

MSB (TEMPh): 96 = 60h
LSB (TEMPl): 97 = 61h
Each LSB of TEMPh represents one degree centigrade. The TEMPh register is to be used in conjunction with TEMPl to yield a
sixteen-bit temperature value. If OEMCFG6 bit 1 is a zero, temperature is read to 1°C resolution in TEMPh only, and TEMPl is
zero. If OEMCFG6 bit 1 is a one, then temperature is read to 0.5°C resolution as a nine-bit value consisting of TEMPh and the
MS bit of TEMPl. The lower seven bits of TEMPl are zero.
