HSS Transmit Gap Register [0xC074] [R/W]
Register Description
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, equiv-
alent to two stop bits.
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, equiv-
alent 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 a Transmit Gap Select Value of 8 is equal to
having one Stop bit.
transmitted bytes. The inactive time = (Transmit Gap Select –7)
* bit time. Therefore a Transmit Gap Select Value of 8 is equal to
having one Stop bit.
Reserved
Write all reserved bits with ’0’.
HSS Data Register
[0xC076] [R/W]
Register Description
The HSS Data register contains data received on the HSS port
(not for block receive mode) when read. This receive data is valid
when the Receive Ready bit of the HSS Control register is set to
‘1’. Writing to this register initiates a single byte transfer of data.
The Transmit Ready Flag in the HSS Control register must read
‘1’ before writing to this register (this avoids disrupting the
previous/current transmission).
