Table 3. User-Programmable Registers
Register address 0Ah is a special-function register.
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
register defines each power-management state. In the
default state, SHDN = 1 shuts down the MAX19506 and
SHDN = 0 returns to full power.
