PDN
Power-down control signal. When PDN is a asserted (logic “0”), both the channel 1 and channel 2 circuits enter
the power-down state. However, even in power-down mode, the state of the control registers is maintained.
Reads and writes to the registers are also possible, and the state of the INT pin also changes in accordance with
inputs from the SLIC devices. This pin is deasserted (logic “1”) by external logic during normal operation.
This power-down function is available even in power saving mode by the MODEn (CR0-B1/CR0-B0) bit.
RESET
An input to reset control registers. By asserting the RESET pin (applying a logic “0”), all control registers are
initialized. During a normal operation mode, set this pin logic “1”.
