DI
Continuous read, sequential read
Function by which data is read from a specified address using a read command, followed by the
output of the next address. This is useful when there is a large amount of user data (ex.: ID codes).
Serial-port direct coupling, microcomputer interface, 8-bit command
The serial port is a serial I/O port provided for a microcomputer. A device that can be easily and
directly coupled to this port is referred to as a “serial-port direct-coupling type” or a “microcomputer
interface.”
Data is input at the rising edge of the SK input clock, and output at its falling edge.
Commands and data are input and output in 8 bits.
This configuration can substantially reduce the number of programs required for the microcomputer.
The advantages are easy programming and a reduced ROM capacity.
