Settings
-
Settings:
- 7-bit addressing: Addressing mode (7-bit addressing / 8-bit addressing (Include R/W in Address) / 10-bit addressing). A wrong setting mis-decodes slave addresses. Default: 7-bit addressing.
- PMBus PEC: Verify Packet Error Code (PEC). Default: cleared.
- Clock Stretching: When checked, enable clock-stretch handling and open Clock Stretching Settings via the gear (shared with I2C / SMBus); gear is disabled (Disable) when cleared. First check often opens the dialog. Default: cleared.
- Clock stretching: Detect when a slave holds SCL low to stretch the clock. Default: cleared.
- Timeout check (Range: 0 ns ~ 67 ms): Flag stretches longer than the limit. When checked, the value field is enabled (Enable) (enter ns, about 0–67 ms); when cleared it is disabled (Disable). Default: cleared, value empty.
- Violation check: Flag non-compliant clock stretching. Default: cleared. Open this dialog from the gear next to Clock Stretching to configure how the analyzer detects or flags clock stretching (a slave holding SCL low so the master waits):
-
Clock stretching: Enable detection of clock stretching. Default: cleared.
- Timeout check (Range: 0 ns ~ 67 ms): Flag a stretch that exceeds the allowed duration. When checked, the value field is enabled (Enable) — enter ns (about 0–67 ms); when cleared the value field is disabled (Disable). Default: cleared, value empty.
- Violation check: Flag non-compliant clock stretching. Default: cleared.
