I2C0RD is a read-only special function register (SFR) to store receive data.
I2C0RD is updated after completion of each reception.

[Description of Bits]

•

I20R7-I20R0

(bits 7

to

0)

The I20R7 to I20R0 bits are used to store receive data. The signal input to the SDA pin is received at transmission of a
slave address and at data transmission/reception in sync with the rising edge of the signal on the SCL pin. Since the
signal of the SDA pin sync with the rising edge of the signal of the SCL pin is received not only at data reception but also
at slave address data transmission and data transmission, it is possible to check whether transmit data has certainly been
transmitted.
