void cfa_bsc_Configure(UINT8 newConfig);
// To configure the I2C serial interface. The configuration values include:
// - Clock Rate
// - Clock divider
// - Delay disable
// - Deglitch disable
CFA_BSC_STATUS cfa_bsc_OpExtended(UINT8* buf,
UINT16 bufCount,
UINT8* addr,
UINT8 addrCount,
UINT8 slaveAdr,
UINT8 operation);
// This function performs blocking read/writes, both addressed and unaddressed
// The amount of data read/written can exceed 8. The address is assumed to be in
// big endian format.
// Input:
// - Pointer to data buffer. For reads, this is where data will be read into
// For writes, data will be written from here.
// - Number of bytes to read/write from the buffer.
// - Pointer to address. Only valid if address count is non-zero; if address count is
// zero, it must be set to 0. This is the address that is sent to the device
// before the operation. In the case of a read, the address is written followed
// by a read. For a write, the address is written, followed by the data.
// The address is assumed to be in big endian format. This is pertinent only
// if the operation requires multiple hardware operations to complete; otherwise
// it is of no significance. The maximum number of bytes that can be read
// in a single hardware transaction is 8 and the maximum that can be written
// is 8 - address size. Note that the address will be modified
// - Number of address bytes. If this is zero, no address is written before the
// operation. If non-zero, the address is written before the read/write. In
// case of a write, the size of the address plus the size of the data must be <= 8
// - Slave address
// - Operation (read/write)
