,BYTE* pReadBuffer, UINT ReadLength)

Parameters:1.

device—Device object pointer as returned by HidUart_Open().

cp2114Address —The OTP address to read from. This address must be in between 0x6800

and 0x7FFFF (inclusive).

pReadBuffer—Pointer to a byte array buffer to store data read from OTP space.

ReadLength—Length of OTP data to read in bytes.

Return Value: HID_UART_STATUS

kilobytes from address 0x6800.

Prototype:

HID_UART_STATUSCP2114_WriteOTP(HID_UART_DEVICE

device,

UINT

cp2114Address ,BYTE* pWriteBuffer, UINT writeLength)

Parameters:1.

device—Device object pointer as returned by HidUart_Open().

cp2114Address —The OTP address to start writing to. This address must be in between

0x6800 and 0x7FFFF (inclusive).

pWriteBuffer—Pointer to a byte array buffer that will contain values to write to the OTP space.

writeLength—The length of write buffer in bytes. The maximum length is 6K bytes.

Return Value: HID_UART_STATUS

HID_UART_SUCCESS
