Register 3 - Address 0011
This register is used to control the sequencing delays from PG1# to PG2#, PG2# to PG3#, and PG3# to PG4#.
The SMH4804 provides two levels of sequencing delay: fast and slow, which is selected by programming bit 3
of Register 9. These two bits are effectively concatenated with R9 bit 3, providing 8 programmable delay periods.
Refer to Register 9 for more information.
NOTE - Bit 1 controls the effect of the MODE pin. When set (high) the pin functions as described in the pin
descriptions. If the bit is cleared (low) the state of the pin is ignored and the circuit breaker enters latch mode.
Bit 0 enables or disables the function of the PD[4:1]# inputs
