If the ES0 bit in the S1D0 register is set to "1" (I
output port. When the PED bit is set to "1" and the SCL
is set to "1". Then the setting values of P2_0 and P2_1 bits in the port P2 register are output to the I
bus, regardless of he internal SCL/SDA output signals. (SCL/SDA pins are onnected to I
circuit)
The bus data can be read by reading the port pi direction register in input mode, regardless of the setting
values of the PED and PEC bits. Table 16.5 shows the port specification.
