The HSS Baud Rate register sets the HSS Baud Rate. At reset, 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)

Reserved

All reserved bits must bit written as ‘0’.

HSS Transmit Gap Register [0xC074] [R/W]

Figure 50. HSS Transmit Gap Register

The HSS Transmit Gap register is only valid in block transmit mode. It allows for a programmable number of stop bits to be inserted

thus overwriting the One Stop Bit in the HSS Control register. The default reset value of this register is 0x0009, equivalent to two stop

bits.

Transmit Gap Select (Bits [7:0])

The Transmit Gap Select field sets the inactive time between transmitted bytes. The inactive time = (Transmit Gap Select – 7) * bit

time. Therefore an Transmit Gap Select Value of 8 is equal to having one Stop bit.

Reserved

All reserved bits must be written as ‘0’.
