[L9369] when to set RST function enable on EN_EL pin (#47)

[haihun]

EN_EL pin (#47) is originally EN function and to set it as RST function， need to set D[4] of reg8Ah.

My question: When to set D[4] to 1 to enable RST function?  should it do after setting watchdog ?

Thanks! 

 

RST Remapping on EN_EL the function of Input reset pin. (Configurable via
SPI at 1st start-up, stored in PROM). Enabled via SPI (EN_EL_RST_EN,
reg8Ah/138d D[4])
