The values of INTV[7:1] are the same for both QSPI and SCI interrupt requests; the
value of INTV0 used during an interrupt acknowledge cycle is supplied by the QSM.
INTV0 is at logic level zero during an SCI interrupt and at logic level one during a QSPI
interrupt. A write to INTV0 has no effect. Reads of INTV0 return a value of one.
SCCR0 contains the SCI baud rate selection field. Baud rate must be set before the
SCI is enabled. The CPU32 can read and write SCCR0 at any time. Changing the val-
ue of SCCR0 bits during a transfer operation can disrupt operation.
SCI baud rate is programmed by writing a 13-bit value to this field. Writing a value of
zero to SCBR disables the baud rate generator. Baud clock rate is calculated as fol-
lows:
SCCR1 contains SCI configuration parameters, including transmitter and receiver en-
able bits, interrupt enable bits, and operating mode enable bits. The CPU can read and
write SCCR1 at any time. The SCI can modify the RWU bit under certain circumstanc-
es. Changing the value of SCCR1 bits during a transfer operation can disrupt opera-
tion.
RESET:
RESET:
0 = Normal SCI operation, no looping, feedback path disabled
1 = Test SCI operation, looping, feedback path enabled
0 = If configured as an output, TXD is a normal CMOS output.
1 = If configured as an output, TXD is an open-drain output.
0 = Short idle-line detect (start count on first one)
1 = Long idle-line detect (start count on first one after stop bit(s))
