7.7.5 Baud Rate Register
Data Sheet
126
NOTE:
NF — Noise Error Flag
FE — Framing Error Flag
Bit 0 — Unimplemented
Use this register to select different baud rates for the SCI system. The SCP[1:0]
(SCP[2:0] in MC68HC(7)11E20) bits function as a prescaler for the SCR[2:0] bits.
Together, these five bits provide multiple baud rate combinations for a given crystal
frequency. Normally, this register is written 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
TCLR — Clear Baud Rate Counter Bit (Test)
SCP[2:0] — SCI Baud Rate Prescaler Select Bits
SCP2 applies to MC68HC(7)11E20 only. When SCP2 = 1, SCP[1:0] must equal 0s.
Any other values for SCP[1:0] are not decoded in the prescaler and the results are
unpredictable. Refer to
RCKB — SCI Baud Rate Clock Check Bit (Test)
NF is set if majority sample logic detects anything other than a unanimous
decision. Clear NF by reading SCSR with NF set and then reading SCDR.
FE is set when a 0 is detected where a stop bit was expected. Clear the FE flag
by reading SCSR with FE set and then reading SCDR.
Always reads 0

0 = Unanimous decision
