TECHNICAL DATA
OR — Overrun Error Flag
OR is set if a new character is received before a previously received character is read
from SCDR. Clear the OR flag by reading SCSR and then reading SCDR.
0 = No overrun
1 = Overrun detected
NF — Noise Error Flag
NF is set if majority sample logic detects anything other than a unanimous decision.
Clear NF by reading SCSR and then reading SCDR.
0 = Unanimous decision
1 = Noise detected
FE — Framing Error
FE is set when a zero is detected where a stop bit was expected. Clear the FE flag by
reading SCSR and then reading SCDR.
0 = Stop bit detected
1 = Zero detected
Bit 0 — Not implemented
Always reads zero
7.6.5 Baud Rate Register
Use this register to select different baud rates for the SCI system. The SCP[1:0] bits
select the prescaler rate for the SCR[2:0] bits. Together, these five bits provide multi-
ple baud rate combinations for a given crystal frequency. Normally, this register is writ-
ten once during initialization. The prescaler is set to its fastest rate by default out of
reset, and can be changed at any time. Refer to Table 7-1 and Table 7-2 for normal
baud rate selections.
TCLR — Clear Baud Rate Counters (Test)
SCP[1:0] — SCI Baud Rate Prescaler Selects
Refer to the SCI baud rate generator block diagram.
