FIFO control register
The FIFO Control Register (FCR) relates the parity error count and the FIFO length.

DESCRIPTION

not used
Parity Error Count: PEC2, PEC1 and PEC0 determine the number of parity errors
before setting the bit PE within the USR and pulling INT0 LOW; 000 means that only
one parity error has occurred and bit PE is set.
6 to 4
The value 000 indicates that if only one parity error has occurred bit PE is set; the value
111 indicates that PE will be set after 8 parity errors.
In protocol T = 0:
If a correct character is received before the programmed error number is reached the
error counter will be reset
If the programmed number of allowed parity errors is reached, bit PE in the USR will
be set as long as the USR has not been read
If a transmitted character has NAKed by the card, then the TDA8030; TDA8031 will
automatically re-transmit it a number of times equal to the value programmed in PEC2,
PEC1 and PEC0. The character will be resent at 15 ETU
In transmission mode, if bits PEC2, PEC1 and PEC0 are at logic 0, then the automatic
re-transmission is invalidated; the character manually rewritten in the UTR will start at
13.5 ETU.
In protocol T = 1:
The error counter has no action; bit PE is set at the first incorrectly received character.
not used
FIFO Length: Bits FL2, FL1 and FL0 determine the depth of the FIFO:
000 = length 1
111 = length 8
