Interrupt Indicator

The RT5016C provides an interrupt indicator output pin (INT). INT is an open-drain output which is controlled by A9.INT

bit. When the PGOOD, TS_Meter [2:0], EOC, THR, SAFE, NoBAT, CHGRUN, DPM status bits toggle, the A9.INT bit

will be set to high. In order to reset the interrupt status, a

“0” must be written to the A9.INT bit or power on the PMU

again. The timing diagram is shown below :

THR

EOC

PGOOD

A9.INT bit is written to "0"

TS_Meter [2:0]

NoBAT

CHGRUN

DPM

SAFE

INT

When the A9.INT bit is written to "0", the INT will be set to high.

When Mask_DPM = 1 and DPM event change, the INT would not be asserted.

(Mask_DPM = 0)
