Section 22 Synchronous/Asynchronous Serial Interface H (UARTH)
Note 1.
Extension bit detection and ID comparison are enabled
(URTHnOPT1.URTHnIDCN = 1) during the transfer of DATA0. The level of the
extension bit differs from the detection condition, so neither a reception
interrupt (URTHnTIR) nor a status interrupt (URTHnTIS) is generated.
Note 2.
Extension bit detection and ID comparison are enabled
(URTHnOPT1.URTHnIDCN = 1) during the transfer of DATA1. The level of the
extension bit and the ID match the respective detection conditions, so a status
interrupt (URTHnTIS) is generated.
Note 3.
In DATA2, data are being received because the ID was matched in DATA1. ID
comparison is disabled (URTHnOPT1.URTHnIDCN = 0) and so will not
proceed. A reception interrupt (URTHnTIR) is generated in response to the
correct reception of DATA2.
Note 4.
Extension bit detection and ID comparison are disabled
(URTHnOPT1.URTHnIDCN = 0) during the transfer of DATA3, but the level of
the extension bit matches the detection condition, so a status interrupt
(URTHnTIS) is generated.
Note 5.
Extension bit detection and ID comparison are enabled
(URTHnOPT1.URTHnIDCN = 1) during the transfer of DATA4, and the level of
the extension bit does not match the detection condition, so neither a reception
interrupt (URTHnTIR) nor a status interrupt (URTHnTIS) is generated.
Note 6.
Extension bit detection and ID comparison are enabled
(URTHnOPT1.URTHnIDCN = 1) during the transfer of DATA5. The level of the
extension bit matches the detection condition but the ID does not, so neither a
reception interrupt (URTHnTIR) nor a status interrupt (URTHnTIS) is
generated.
Caution 1.
If a reception error (parity, framing, or overrun error) had occurred during the
reception of DATA2, the error flag would have been set and a status interrupt
request (URTHnTIS) generated instead of a reception completed interrupt
request (URTHnTIR).
Caution 2. If a reception error (parity, framing or overrun error) had occurred during the
reception of DATA1 and DATA3, the error flag would have been set (along with
URTHnIDM or URTH0EBD). If a reception error occurred during DATA0,
DATA4, or DATA5, the error flag would not have been set.
