PMBus Command Description

MFR_WATCHDOG_T_FIRST and MFR_WATCHDOG_T Data Contents

BIT(S) SYMBOL

OPERATION

b[15:0] 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 10µs 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 0.6 sec for _t and 65 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=0xFF) is in use.
