Bits 2 to 0: Transmit Low Watermark Select Bits (TLWMS[2:0]). These control bits determine when the HDLC
controller should set the TLWM status bit in the HSR register. When the transmit FIFO contains less than the
number of bytes specified by these bits, the TLWM status bit is set to logic 1.

Bits 4 to 6: Receive High Watermark Select Bits (RHWMS[2:0]). These control bits determine when the HDLC
controller should set the RHWM status bit in the HSR register. When the receive FIFO contains more than the
number of bytes specified by these bits, the RHWM status bit is set to logic 1.

Bit 2: Transmit FIFO Low Watermark (TLWM). This real-time status bit is set to a 1 when the transmit FIFO
contains less than the number of bytes configured by TLWMS[2:0] control bits in the HCR2 register. This bit is
cleared when the FIFO fills beyond the low watermark.
Bit 3: Receive FIFO High Watermark (RHWM). This real-time status bit is set to a 1 when the receive FIFO
contains more than the number of bytes configured by the RHWMS[2:0] control bits in the HCR2 register. This bit is
cleared when the FIFO empties below the high watermark.
