• I20R7-I20R0 (bits 7-0)
Address: 0F2A0H
Access: R
Access size: 8 bits
Initial value: 00H
I2C0RD is a read-only special function register (SFR) to store receive data.
I2C0RD is updataed after completion of each reception.
[Description of Bits]
Initial value
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 data that has been output to the SDA and SCL pins 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.
