CS0
Checksum 0
There are multiple Start register and Checksum (CS0/CS1/CS2/CS3) registers for different crucial register blocks. Those registers are handled in
the similar way.

ENERGY CALIBRATION REGISTERS
Address: 3BH
Type: Read/Write
Default Value: 421CH

Description
15 - 0
CS0[15:0]
This register should be written after the 31H-3AH registers are written. Suppose the high byte and the low byte of the 31H-3AH
registers are shown in the below table.
The calculation of the CS0 register is as follows:
The low byte of 3BH register is: L3B=MOD(H31+H32+...+H3A+L31+L32+...+L3A, 2^8)
The high byte of 3BH register is: H3B=H31 XOR H32 XOR... XOR H3A XOR L31 XOR L32 XOR... XOR L3A
The 90E36 calculates CS0 regularly. If the value of the CS0 register and the calculation by the 90E36 is different when Config-
Start=8765H, the CS0Err bit (b14, SysStatus0) is set and the WarnOut and IRQ pins are asserted.
Note: The readout value of the CS0 register is the calculation by the 90E36, which is different from what is written.
