Device Addressing
To start communication, the master device (MPU) on the system generates a start condition for the slave device
(S-7750C). After that, the master device sends a device address with 7-bit and Read / Write instruction code with 1-bit on
the SDA bus. The higher 3 bits in a device address (DC2, DC1, DC0) are device codes. The fixed value which users
selected by option (either one of 000, 001, 010, 011, 100, 101, 110, 111) is a device code. Command is omitted if a
device code does not correspond. The next 1-bit
C
TA /
is a bit for timer address setting / command switch.
When
C
TA /
= “1”, the next 3 bits (C2, C1, C0) are used as address, when
C
TA /
= “0”, (C2, C1, C0) are used as
command for the timer setting register.
