HIGH PERFORMANCE 2.97V TO 5.5V OCTAL UART
This is a 8-bit general purpose register for the user to store temporary data. The content of this register is
preserved during sleep mode but becomes 0xFF (default) after a reset or a power off-on cycle.
This register controls the UART enhanced functions that are not available on ST16C554 or ST16C654.
FCTR [3:0] - Auto RTS/DTR Flow Control Hysteresis Select
These bits select the auto RTS/DTR flow control hysteresis and only valid when TX and RX Trigger Table-D is
selected (FCTR bit-6 and 7 are set to logic 1). The RTS/DTR hysteresis is referenced to the RX FIFO trigger
level. After reset, these bits are set to logic 0 selecting the next FIFO trigger level for hardware flow control.
