Compiling and understanding Hex codes for TI BQ20z80 chipset

[Davepix]

I’m trying to understand how to create the hex codes necessary to change parameters as well as understand codes that are reported back by the BMS/chipset.

For example, how would I create a hex code to write parameters from the register below, say, to write ZVCHG1 and CHGLED high and all the rest low or is it when bit 3 is low it’s CHGLED and high would be SLEEP?

The particular code I need to modify is following and I do wish to modify ZVCHG and SVCHG0 between each of the four choices to see if what they are connected to operats correctly. Operation Cfg A = 1E60 also B and C take hex codes and I’m pretty clueless as to how 1E60 is derived from the below table or parameters.



Operation Cfg A
This register is used to enable or disable various functions on the bq20z80.  These bits are continued in B.

LEDR	LEDRCA	CHGLED	DMODE	LED1	LED0	CC1	CC0
-	-	SLEEP	TEMP1	TEMP0	SLED	ZVCHG1	ZVCHG0

n       ZVCHG1,0 [1,0]:   These bits are also known as Pre-Charge 1,0.  These bits are used to tell the bq20z80 how the Pre-Charge circuit is configured in the application.  In other words it tells the bq2z80 what pin on the bq29312A to use for Pre-Charge functions when required.
•         1,1 =  No action is taken in Pre-Charge functions with this setting.
•         1,0 =  OD pin is used for Pre-Charge functions.
•         0,1 =  Charge FET is used for Pre-Charge functions.
•         0,0 =  ZVCHG FET is being used for Pre-Charge functions
Normal Setting:  If using a separate Pre-Charge FET it is highly recommended not to use the OD pin for this function because it does not have good “zero volt charging” capabilities when a battery is completely dead.  Therefore the ZVCHG pin should be used because it has excellent clamping abilities.  The default is for using the Charge FET pin on the bq29312A.
