Registers

The MC34016 is equipped with two 8–bit registers which

are selected by the value of the most significant bit (Bit 7). If

the supply voltage of the MC34016 drops below 2.5 V, all

registers are set to 0. This RESET function enables a smooth

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ power–up of the device. The registers are as follows:

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ Register 1 (Bit 7 = 0)
