MFR_WATCHDOG_T_FIRST and MFR_WATCHDOG_T Data Contents
BIT(S) SYMBOL OPERATION
b[15:0] Mfr_watchdog_t_first
Mfr_watchdog_t
The data uses the L11 format.
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.
