Disable watchdog in FS85

[ponnitresa_kuri]

Hi,

I am working on PMIC which is interfaced with SPI.

I would like to know how to disable the PMIC watchdog durning reprogramming of MCU.

Can any one send sequence of commands to disable the watchdog.

Hi

You can enter into DEBUG mode for software debug.

In datasheet page14 REV0.8

----

14.5 Debug mode
The FS85/FS84 enters in Debug mode with the sequence described in Figure 8:
1. DBG pin = VDBG and VSUP > VSUP_UVH
2. WAKE1 or WAKE2 > WAKE12VIH
VDBG and VSUP can come up at the same time as long as WAKE1 or WAKE2 comes up

Thanks!
