Receiver character length is loaded by the processor when RxCLE = 0. The character length is
valid after transmission of single byte address and control fields have been received.
Receiver character length enable should be zero when the processor loads RxCL. The
remaining bits of PCR are not affected during loading. Always 0 when read.
Transmitter character length enable should be zero when the processor loads TxCL. The
remaining bits of PCR are not affected during loading. Always 0 when read.
Transmitter character length is loaded by the processor when TxCLe = 0. Character bit length
specification format is identical to RxCL. It is valid after transmission of single byte address and
control fields.
