This data field acts as serial shift register and read buffer for
interfacing to the I
I
combination of a shift register and a data buffer. 8-bit parallel data is
always written to the shift register, and read form the data buffer. I
bus data is always shifted in or out of the shift register.
Not applicable.
This prescaler value is used to generate the serial I
system clock is divided by (16 x (prescaler value + 1) + 3) to make the
serial I
divided by 19 to make the serial I
