Processing Specifications of Sample Program for Extended Intelligent I/O Service
(EI
2
OS)
1. This program detects the H level signal input to the INT0 pin and activates the extended intelligent I/O
service (EI
2
OS).
2. When the H level is input to the INT0 pin, EI
2
OS is activated. Data is transferred from port 0 to the
memory at the 3000
H
address.
3. The number of transfer data bytes is 100 bytes. After 100 bytes are transferred, an interrupt is generated
because EI
2
OS transfer has terminated.
