3. Pin Description

Pin Name

I/O

Function

/RESET

I

IC reset input, low active.

BP00 ~ BP07

I/O



General input/output pins.



Each pin can be set as Input or Output individually.



When the pin will be set output by BP0D, user needs to set

BP0x value of 0/1 first.



For output pin, BP0 provides high-sink current.



For input pin, it can be set as pull-high or floating



BP00/02/04 can be set as 3-pin H/W PWM output with 64-

level resolution. They can be paired with BP01/03/05 (also

H/W PWM output) respectively with same or opposite phase

of output waveform



BP07 can be configured as IR carrier output

BP10 ~ BP17

I/O



General input/output pins.



Each pin can be set as Input or Output individually.



When the pin will be set output by BP1D, user needs to set

BP1x value of 0/1 first.



For input pin, it can be set as pull-high or floating.



BP1 can generate interrupt request to release IC from STOP

mode

*BP20 ~ BP27

I/O



General input/output pins.



Each pin can be set as Input or Output by group, BP20 ~ BP23

configured by BP2D[0], and BP24 ~ BP27 by BP2D[1].



When the pin will be set output by BP2D, user needs to set

BP2x value of 0/1 first.
