Host confirms the B_BUSY bit in BTCR.
Host confirms the H2B_ATN bit in BTCR.
Host clears write pointer by setting the CLR_WR_PTR
bit in BTCR.
Host writes data of 1 to n bytes to the BTDTR buffer.
Host sets the H2B_ATN bit in BTCR to indicate data write
completion to the buffer for the BT interface.
