4. I²C Bus Option [H8/3337 Series]
I²C bus used
I²C bus not used
Notes: 1. “I²C bus used” includes all cases where data transfer is performed by means of the SCL
and SDA pins using the on-chip I²C bus interface function (hardware module). As long
as the I²C bus interface function (hardware module) is used, various bus interfaces with
different bus specifications and names are also included in “I²C bus used”.
2. If “I²C bus not used” is selected, values cannot be set in I²C bus interface related
registers (ICCR, ICSR, ICDR, and ICMR). These registers return H’FF if read.
In the case of an emulator and the ZTAT and F-ZTAT versions, the “I²C bus used”
option is taken as being selected. If the “I²C bus not used” option is selected, care must
be taken to confirm that I²C bus interface related registers are not accessed.
For (1) Basic Items and the Microcomputer Family item in the “Single-Chip Microcomputer
