Bits 7 CTS# state change
This bit is set whenever CTS# input has changed state, and it will be reset if the CPU reads
the MSR.
Whenever either of MSR[4:7] is set to logic 1, a Modem Status Interrupt is generated if IER[4]=1.
Writing LSR is a null operation (not suggested).

Bits 0 Time-Out (interrupt) enable
The feature of Receiver Time-Out (interrupt) is enable only when TOR[0] = IER[7] = 1.
Bits 1-7 Time-Out (interrupt) comparator
The Time-Out counter is reset and start counting (the counting clock = baud rate) whenever
the RX FIFO receives a new data word. Once the content of Time-Out counter (TOUT_cnt)
is equal to that of Time-Out comparator (TOUT_cmp), a Receiver Time-Out interrupt Irpt_
TOUT) is generated if TOR[0] = IER[7] = 1.
A new incoming data word or RX FIFO empty clears Irpt_TOUT.
6.8 SYNCHRONOUS SERIAL INTERFACE REGISTERS
There are five registers included in the Synchronous Serial Interface (SSI) controller. The IO address map is
allocated from 0xf0000380 to 0xf000038a.
