Description
Bit Counter 2 to 0
These bits specify the number of bits to be transferred
next. When read, the remaining number of transfer bits
is indicated. With the I
transferred with one addition acknowledge bit. Should
be made between transfer frames. If bits BC2 to BC0
are set to a value other than 000, the setting should be
made while the SCL pin is low. The value returns to 000
at the end of a data transfer, including the acknowledge
bit. These bits are automatically set to 111 after a stop
condition is detected. These bits are cleared by a
power-on reset and in standby mode. These bits are
also cleared by setting IICRST of ICCR2 to 1. With the
clock synchronous serial format, these bits should not
be modified.
