Initialization

q X: This bit is not used here. Set it to “0” or “1” arbitrarily.

• Serial I/O2 setting

Read out reception data from

TB/RB (address 001F16)

Read out reception data from

TB/RB (address 001F16)

• SRDY2 output

SRDY2 signal is output by writing data to

the TB/RB.

When using SRDY2, set Transmit enable

bit (bit4) of SIO2CON to “1.”

• An interval of 2 ms generated by Timer.

• Judgment of completion of receiving

(Receive buffer full flag)

• Reception of the first byte data.

Receive buffer full flag is set to “0” by reading

data.

• Judgment of completion of receiving

(Receive buffer full flag)

• Reception of the second byte data.

Receive buffer full flag is set to “0” by reading data.
