4.6.2 Special function registers for serial port
4.6.2.1 SCON (Serial Port Control Register)
SCON is an 8-bit special function register consisting of control bits for specifying serial port
operation modes and enabling/disabling data reception, storage bits for the ninth data bit
transmitted and received during 11-bit frame UART mode, and the serial port status flag.
In addition to specifying SCON by data address 98H, each bit can be specified by bit
addresses.
The functions of each SCON bit are listed in Table 4-15, and the functions of each operational
mode specified by SCON are indicated in Table 4-16.
