SERIAL I/O
The 3819 group has built-in 8-bit clock synchronized serial I/O ! 3
channels (serial I/O1, serial I/O2, and serial I/O3).
Serial I/O1 builds in the automatic transfer function. The function
can be switched to the serial I/O ordinary mode with the serial I/O
automatic transfer control register (address 001A16).
Serial I/O2 and Serial I/O3 can be used only in the serial I/O ordi-
nary mode.
The I/O pins of the serial I/O function are also used as I/O ports
P5 and P64–P67, and their operation is selected with the serial I/O
control registers (addresses 001916, 001D16, and 001E16).
Serial I/O Control Registers
(SIO1CON, SIO2CON, SIO3CON)
001916, 001D16, 001E16
Each of the serial I/O control registers (addresses 001916,
001D16, and 001E16) consists of 8 selection bits which control the
serial I/O function.
