DM6581/82 Pin Description
Pin No.
Pin Name
I/O
1
RD_SP2
I
Data Input Pin Of Serial Port 2:
The serial data is sampled at the falling edge of the SCLK. The
MSB is coming immediately after falling of FR_SP2 signal.

FR_SP2
I/O
Frame Signal For Serial Port 2:
This pin is used to indicate a data transfer. It remains in a low
state until the rising edge of SCLK is detected. A high to low
transition initiates a data transfer.
