CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Serial Interface)
7-bit asynchronous mode
In this mode, 7-bit asynchronous transfer can be performed. Parity check during data reception and
addition of parity bit (odd/even/none) during transmitting can be specified and data processed in 7
bits with or without parity. Since this mode employs the internal clock, the SCLK terminal is not used.
Furthermore, since the SRDY terminal is not utilized either, both of these terminals can be used as I/O
ports.
Figure 4.11.3.1(c) shows the connection example of input/output terminals in the asynchronous mode.
8-bit asynchronous 8-bit mode
In this mode, 8-bit asynchronous transfer can be performed. Parity check during data reception and
addition of parity bit (odd/even/none) during transmitting can be specified and data processed in 8
bits with or without parity. Since this mode employs the internal clock, the SCLK terminal is not used.
Furthermore, since the SRDY terminal is not utilized either, both of these terminals can be used as I/O
ports.
Figure 4.11.3.1(c) shows the connection example of input/output terminals in the asynchronous mode.
