SA56004X
Digital temperature sensor with overtemperature alarms
7.8.5   Conversion rate register (CR)
The conversion rate register is used to store programmable conversion data, which
defines the time interval between conversions in the standard free-running auto convert
mode. Table 10
 shows all applicable data values and rates for the SA56004X. Only the
4 LSBs of the register are used and the other bits are reserved for future use. The register
is R/W using the read address 04h and write address 0Ah. The POR default conversion
data is 08h.
 
7.8.6   Temperature limit registers
 
[1]   POR default LHS = RHSHV = 46h (70 癈).
[2]   POR default RHSLB = 00h.
 
[1]   POR default LLS = RLSHV = 00h.
[2]   POR default RLSLB = 00h (0 癈).
 
[1]   POR default LCS = RCS = 55h (85 癈).
