Slave confirms the H_BUSY bit in BTCR.
Slave writes data of 1 to n bytes to the BTDTR
buffer.
Slave sets the B2H_ATN bit in BTCR to indicate
data write completion to the BTDTR buffer.
The HBTRI bit in BTSR0 is set to notify host reads
all data through the BTDTR buffer.
Confirms the CLR_RD_PTR bit.
The CRRPI bit in BTSR1 is set to notify read
pointer clearing as an interrupt source to slave.
Confirms the B2H_ATN bit.
The B2HI bit in BTSR1 is set to notify host data
read completion as an interrupt source to slave.

Host confirms the B2H_ATN bit in BTCR.
The slave data write completion interrupt is notified to host.
Host sets the H_BUSY bit in BTCR.
Host clears read pointer by setting the CLR_RD_PTR
bit in BTCR.
Host waits for the B2H_ATN bit (interrupt from

Host reads data from the BTDTR buffer.
Host clears the B2H_ATN bit in BTCR.
Host clears the H_BUSY bit in BTCR to indicate
