D7
Sleep
X
(when 0x40
D4 = 1)
Key-switch operating mode. Key switches always remain active
when constant-current PWM is enabled (bit 4 of register 0x40 is
high) regardless of autosleep, autowakeup, or an I2C write to this bit.
0
(when 0x40
D4 = 0)
Key-switch sleep
mode. The entire
chip is shut down.
When constant-current PWM is disabled
(bit 4 of register 0x40 is low), I2C write,
autosleep, and autowakeup all can change
this bit. This bit can be read back by I2C
any time for current status.

INTK cleared after host read. In this mode, I2C should read the
FIFO until interrupt condition is removed or further INT may be lost.
