Table 3. User-Programmable Registers

Writing data 5Ah to register 0Ah initiates a register

reset. When this operation is executed, all control regis-

ters are reset to default values. A read operation of reg-

ister 0Ah returns a status byte with information

described in Table 2.

The SHDN input (pin 7) toggles between any two

power-management states. The Power Management

default state, SHDN = 1 shuts down the MAX19515 and

SHDN = 0 returns to full power.
