PIN DESCRIPTION
PIN NAME
I/O
FUNCTION
RESETB
In
IC reset input.
XIN
In
Sub-clock oscillation input.
XOUT
Out
Sub-clock oscillation output.
XSEL
In
Pin selection of sub-clock type. When XSEL is logic 1, RC type is used.
When XSEL is logic 0, crystal type is used.
OSCI
In
Main-clock oscillation input.
OSCO
Out
Main-clock oscillation output.
OSCSEL
In
Pin selection of main-clock type. When OSCSEL is logic 1, Ring type is
used. When OSCSEL is logic 0, crystal type is used.
IP0[7:0]
In
General input port with pull-high selection. Each input pin can be
programmed to generate interrupt request and used to release IC from
HOLD/STOP mode.
IP0.6 can be used as the external clock source of the general timer
TimerG.
BP0[7:0]
I/O
General input/output pins. When used as output pin, it can be open–
drain or CMOS type and it can sink 8mA for high-current application.
When used as input pin, there may have a pull-high option and generate
interrupt request to release IC from HOLD/STOP mode.
When BP0[7] is used as output pin, it can be the IR transmission carrier
for firmware IR application.
BP1[7:0]
I/O
General input/output pins. When used as output pin, it can be open–
drain or CMOS type. When used as input pin, there may have a pull-high
option and generate interrupt request to release IC from HOLD/STOP
mode.
DAC+

TEST
In
Test input. Do not connect during normal operation.
VDD
Power

OVDD
Power
Positive power supply for oscillation.
OVSS
Power
Negative power supply for oscillation.
PVDD
Power
Positive power supply for speaker output.
PVSS
Power
Negative power supply for speaker output.
