The data on the RX/DT pin is sampled three times by a majority detect circuit to determine if a
high or a low level is present at the RX pin.
circuit. The sampling operates the same regardless of the state of the BRGH bit, only the source
of the x16 clock is different.
Figure 18-6:
All new devices will use the sampling scheme shown in
tion to the above sampling scheme are:
• PIC16C63
• PIC16C65
• PIC16C65A
• PIC16C73
• PIC16C73A
• PIC16C74
• PIC16C74A
These devices have a sampling circuitry that works as follows. If the BRGH bit (TXSTA<2>) is
clear (i.e., at the low baud rates), the sampling is done on the seventh, eighth and ninth falling
edges of a x16 clock
is done on the 3 clock edges preceding the second rising edge after the first falling edge of a x4
clock
