Description
0: RC Oscillator.
1: Crystal Oscillator.
0: Slow clock enable
1: Slow clock disable
With two clock sources available, the system can switch among operation modes of Normal, Slow, Idle,
and Sleep modes by the setting of OP1 and OP2 registers as shown in tables below to suit the needs of
application such as power saving, etc.

6. General Purpose I/O
The PRTC[7..0] and PRTD[7..0] are dedicated general purpose I/O port. All the I/O ports are
bi-directional and non-tristate output structure. The output has weak sourcing (50µA) and stronger
sinking (1mA) capability and each can be configured as push-pull or open-drain output structure
individually by mask option.
When the I/O port is used as input, the weakly high sourcing can be used as weakly pull-up. Open drain
can be used if the pull-up is not required and let the external driver to drive the pin. Please note that a
floating pad could cause more power consumption since the noise could interfere with the circuit and
cause the input to toggle. A ‘1’ needs to be written to port first before reading the input data from the I/O
wwpwi.nD.aItafSthheeet4PUM.coOmS is used as pull-up, care should be taken to avoid the constant power drain by DC path
between pull-up and external circuit.
The input port has built-in Schmidt trigger to prevent it from chattering. The hysteresis level of Schmidt
trigger is 1/3*VDD.

The PWM output volume can be adjusted by command register PWMC[6..4]. The PWMC[6] and
PWMC[5] control 2 time driver, while PWMC [4] controls 1 time driver, thus it has maximum 5 levels of
driver output. The sound volume of PWM output can be controlled by these PWMC[6..4] bits. Please
note that this adjustment only apply to PWM. When the system enters into sleep mode or idle mode, it
will automatically disable all voice outputs by clearing VOC[6..0] to ”0000000”. To activate voice
output again when returning to normal mode, the VOC register needs to be set again.
