PMBus COMMAND DESCRIPTION
MFR_WATCHDOG_T_POR and MFR_WATCHDOG_T Data Contents
BIT(S) SYMBOL
OPERATION
b[1ꢀ:±] Mfr_watchdog_t_first The data uses the L11 format.
Mfr_watchdog_t
These timers operate on an internal clock. The Mfr_watchdog_t timer will align to SHARE_CLK if it is running.
Delays are rounded to the nearest 1±µs for _t and 1ms for _t_first.
Writing a zero value for Y to the Mfr_watchdog_t or Mfr_watchdog_t_first registers will disable the watchdog timer.
Units: ms. Max timeout is ±.6 sec for _t and 6ꢀ sec for _t_first
MFR_PAGE_FF_MASK
The MFR_PAGE_FF_MASK command is used to select which channels respond when the global page command
(PAGE=±xFF) is in use.
