Data Sheet
RX
TX
ISW(15:0)
Receive interrupt
This bit indicates that a receive interrupt occured:
RX=’0’
RX=’1’
Transmit interrupt
This bit indicates that a transmit interrupt occured:
TX=’0’
TX=’1’
Interrupt Status Word
The contents of this bit field depends on the SSC interrupt type:
Type:
error int.
(D/E=’0’)
receive int.
(D/E=’1’,
R/T=’1’)
transm. int.
(D/E=’1’,
R/T=’0’)
No receive interrupt is indicated by this vector.
A receive interrupt is indicated by this vector.
Bit field 15..0 contains the corresponding bit field 15..0 of
register SSCRB (receive buffer containing the received
data bits).
No transmit interrupt is indicated by this vector.
A transmit interrupt is indicated by this vector.
Bit field 15..0 contains a constant zero value. This
interrupt means, that the transmit buffer can be reloaded
with new transmit data (register SSCTB).
Meaning:
ISW(15:0) = SSCCON(15:0)
(Register SSCCON in operational mode.)
ISW(15:0) = SSCRB(15:0)
(Register SSCRB.)
ISW(15:0) = 0000
