Description
These bits are reserved and should be written with zeroes.
The Underflow bit is used to enable the interrupt associated with an underflow condition associated with the Transmit
SERDES Data register (Reg 0x0F)
An underflow condition occurs when attempting to transmit while the Transmit SERDES Data register (Reg 0x0F) does not
have any data.
The Overflow bit is used to enabled the interrupt associated with an overflow condition with the Transmit SERDES Data
register (0x0F).
An overflow condition occurs when attempting to write new data to the Transmit SERDES Data register (Reg 0x0F) before
the preceding data has been transferred to the transmit shift register.
The Done bit is used to enable the interrupt that signals the end of the transmission of data.
The Done condition occurs when the Transmit SERDES Data register (Reg 0x0F) has transmitted all of its data and there
is no more data for it to transmit.
The Empty bit is used to enable the interrupt that signals when the Transmit SERDES register (Reg 0x0F) is empty.
The Empty condition occurs when the Transmit SERDES Data register (Reg 0x0F) is loaded into the transmit buffer and
it's safe to load the next byte
1 = Underflow interrupt enabled.
0 = Underflow interrupt disabled.
1 = Overflow interrupt enabled.
0 = Overflow interrupt disabled.
1 = Done interrupt enabled.
0 = Done interrupt disabled.
