Register 10 is used to configure the SYNC/MODE pin as a synchronization input or output and to configure hiccup protection for each

channel. The default value for hiccup protection can be programmed by factory fuse (hiccup function enabled or disabled for all four

buck regulators).

Bits Bit Name Access Description

7 SYNC_OUT R/W The default value can be programmed by factory fuse.

0 = configure the SYNC/MODE pin as a clock synchronization input if a clock is connected (default).

1 = configure the SYNC/MODE pin as a clock synchronization output.

[6:4] Reserved R/W Reserved.

3 HICCUP4_OFF R/W The default value can be programmed by factory fuse.

0 = enable hiccup protection for Channel 4.

1 = disable hiccup protection for Channel 4 (short-circuit protection is disabled automatically).

2 HICCUP3_OFF R/W The default value can be programmed by factory fuse.

0 = enable hiccup protection for Channel 3.

1 = disable hiccup protection for Channel 3 (short-circuit protection is disabled automatically).

1 HICCUP2_OFF R/W The default value can be programmed by factory fuse.

0 = enable hiccup protection for Channel 2.

1 = disable hiccup protection for Channel 2 (short-circuit protection is disabled automatically).

0 HICCUP1_OFF R/W The default value can be programmed by factory fuse.

0 = enable hiccup protection for Channel 1.

1 = disable hiccup protection for Channel 1 (short-circuit protection is disabled automatically).
