Status of generation of RFS pulses
Only valid when RFIN = 0 (RFS pulses internally generated) and used if
RCONT bit in RFS mode register is ‘0’.
A ‘1’ indicates that generation of pulses as a result of a previous STR
command is still on-going.
This function may be used in connection with the HDLC controller when a
predefined number of data units (e.g. words) are received, clocked by RFS
pulses.
Set:
Reset: 16 bit periods after the last RFS pulse, after hardware reset.
Status of generation of TFS pulses
Only valid when TFIN = 0 (TFS pulses internally generated) and used if
TCONT bit in TFS mode register = 0.
A ‘1’ indicates that generation of pulses as a result of a previous STX
command is still on-going; STX is reset to ‘0’ 16 bit periods after the last TFS
pulse has been generated.
This function may be used in connection with the HDLC controller when a
predefined number of data units (e.g. words) are to be transmitted, clocked
by TFS pulses.
Set:
Reset: 16 bit periods after the last TFS pulse, after hardware reset.
With the rising edge of the first RFS pulse being generated.
With the rising edge of the first TFS pulse being generated.
