PTYPE is an option for the polling method.
Positions (1) to (9) above are trigger points for the following conditions.
(1) SOF End position of the start bit of a PTYPE or PID field
(2) Every PTYPE End position of the stop bit of a PTYPE field
(3) No Response End position of the 10th consecutive bit with logical value 1 counted
from the end position of the stop bit of the PTYPE field
(4) ID End position of the stop bit of a PID field
(5) Sleep frame End position of the stop bit of a CRC field
(6) Wakeup End position of the stop bit of a frame information field
(7) Sleep End position of the stop bit of a frame information field
(8) CT End position of the stop bit of a frame information field
(9) Data (when Size = 0) End position of the stop bit of a extension DLC field
(10) Data (when Size ≠ 0) End position of the stop bit of a specified data bytes field

Positions (1) to (7) above are trigger points for the following errors.
(1) Fraiming Error End position of the bit corresponding to the stop bit of each field
(2) Parity Error End position of a PTYPE or PID stop bit
(3) IBS Error End position of the 10th consecutive logical value 1 bit from the end
position of the stop bit of each field (excluding PTYPE)
(4) Data Length Error
(When data length < DLC)
End position of the 10th consecutive bit with logical value 1 counted
from the end position of the stop bit of the last data bytes field
(5) CRC Error End position of the stop bit of a CRC field
(6) Counter Error
*
End position of the stop bit of a CRC field
(7) Data Length Error
(When data length > DLC)
End position of the start bit of an exceeding byte field
* Counter Error is not a trigger point but a counter error detection point.
