Table 29. Charge Status Register (0x3A)
Address
and Bit
Register Field Name
R/W
Default
Value
Function and Description
0x3a [7:0]
SSChargeStau
RW
0x00
In RX mode the AP writes this register with the value intended to be
sent as payload to the Charge Status Packet. The FW does not verify or
modify the value in any way. The value should be filled based on the
following:
0x0 = Reserved
0x1 = Charge status packet sent with parameter = 1 (1%)
0x2 = Charge status packet send with parameter = 2 (2%)
…
0x64 = Charge status packet send with parameter = 100 (100%)
0x65-0xFE = Reserved
0xFF = No battery charge device or not providing charge status packet
Note
: After writing to this register, Send Charge Status bit of Command Register (0x4E) needs to be set for
transmission to begin.
Table 30. End of Power Transfer Code Register (0x3B)
Address
and Bit
Register Field Name
R/W
Default
Value
Function and Description
0x3b [7:0]
EPTCode
R/W
0x00
In RX mode the AP writes this register with the value intended to be
sent as payload to the Charge Status Packet. The FW does not verify
or modify the value in any way.
A WPC End of Power Transfer packet/message will be sent based on
the following:
0 = WPC mode, unknown EPT should be sent.
1 = WPC mode, End of Charge EPT packet should be sent.
2 = WPC mode, Internal Fault EPT packet should be sent.
3 = WPC mode, Over Temperature EPT packet should be sent.
4 = WPC mode, Over Voltage EPT packet should be sent.
5 = WPC mode, Over Current EPT packet should be sent.
6 = WPC mode, Battery Failure EPT packet should be sent.
7 = WPC mode, Reconfiguration EPT packet should be sent.
8 = WPC mode, No Response EPT packet should be sent.
9-254 = Reserved

Vout ADC
R
–
12-bit of current main LDO Vout ADC value. Vout = ADC_Vout
Value/4095*10*2.1(V)
Table 32. Vout Set Register (0x3E)
Address
and Bit
Register Field Name
R/W
Default
Value
Function and Description
0x3e [15:0]
Vout_Set
R/W
–
Set the output voltage of the main LDO.
VoutSet = (Vout_mV - 2800)*10/84
AP through this register, target Vrect will be automatically set for best
efficiency.
