Status Register SCF
This bit addressable register contains the status bits.
Special Function Registers SCF (Address F8H)
Reset Value : XXXXXX00B
Bit
Function
Not implemented. Reserved for future use. During reads these bits
will be undefined.
WCOL
Write Collision Detect
If WCOL is set it indicates that an attempt was made to write to the
shift register STB while a data transfer was in progress and not fully
completed. This bit will be set at the trailing edge of the write signal
during the erronous write attempt.
This bit can be reset in two different ways :
1. writing a "0" to the bit (bit access, byte access or read-modify-
write access);
2. by reading the bit or the status register, followed by a write
access to STB.
If bit WCEN in the SCIEN register is set, an interrupt request will be
generated if WCOL is set.
TC
Transfer Completed
If TC is set it indicates that the last transfer has been completed. It is
set with the last sample clock edge of a reception process.
This bit can be reset in two different ways:
1. writing a "0" to the bit (bit access, byte access or read-modify-
write access) after the receive buffer register SRB has been read;
2. by reading the bit or the status register, followed by a read
access to SRB.
If bit TCEN in the SCIEN register is set, an interrupt request will be
generated if TC is set.
