Transmit Ready (Bit 4)
The Transmit Ready bit is a read only bit that indicates if the HSS Transmit FIFO is ready for the CPU to load new data for trans- mission.
1:HSS transmit FIFO ready for loading
0:HSS transmit FIFO not ready for loading
Packet Mode Select (Bit 3)
The Packet Mode Select bit selects between Receive Packet Ready and Receive Ready as the interrupt source for the RxIntr interrupt.
1:Selects Receive Packet Ready as the source
0:Selects Receive Ready as the source
Receive Overflow Flag (Bit 2)
The Receive Overflow Flag bit indicates if the Receive FIFO overflowed when set. This flag can be cleared by writing a ‘1’ to this bit.
HSS Baud Rate Register [0xC072] [R/W]
Table 91. HSS Baud Rate Register
1:Overflow occurred
0:Overflow did not occur
Receive Packet Ready Flag (Bit 1)
The Receive Packet Ready Flag bit is a read only bit that indicates if the HSS receive FIFO is full with eight bytes or not.
1:HSS receive FIFO is full
0:HSS receive FIFO is not full
Receive Ready Flag (Bit 0)
The Receive Ready Flag is a read only bit that indicates if the HSS receive FIFO is empty or not.
1:HSS receive FIFO is not empty (one or more bytes is reading for reading)
0:HSS receive FIFO is empty

The HSS Baud Rate register sets the HSS Baud Rate. At reset, | Write all reserved bits with ’0’. |

the default value is 0x0017 which sets the baud rate to 2.0 MHz. |

Baud (Bits [12:0])
The Baud field is the baud rate divisor minus one, in units of 1/48 MHz. Therefore the Baud Rate = 48 MHz/(Baud + 1). This puts a constraint on the Baud Value as follows:
(24 – 1) ≤ Baud ≥ (5000 – 1)
