Setting of Standard Serial I/O Mode 1
Signal
CNVSS
RESET
SCLK
SCLK input
TXD output
BUSY output
RXD input
Reset input
Notes:
1. Control pins and external circuitry will vary according to a programmer. For more information, see the programmer manual.
2. In this example, modes are switched between single-chip mode and standard serial I/O mode by controlling the CNVSS pin
input with a switch.
3. If in standard serial I/O mode 1 there is a possibility that the user reset signal will go low during serial I/O mode,
break the connection between the user reset signal and RESET pin by using, for example, a jumper switch.
