Pull-high*
Wake-up
CMOS/schmitt
trigger input
Bidirectional 8-bit input/output port. Each bit can be
configured as wake-up input by ROM code option.
Software instructions determine the CMOS output or
schmitt trigger or CMOS (dependent on options) input
with a pull-high resistor (determined by pull-high op-
tions).

I/O
Pull-high*
I/O or BZ/BZ
Bidirectional 8-bit input/output port. Software in-
structions determine the CMOS output or schmitt
trigger input with a pull-high resistor (determined by
pull-high options).
The PB0 and PB1 are pin-shared with the BZ and BZ,
respectively. Once the PB0 and PB1 are selected as
buzzer driving outputs, the output signals come from
an internal PFD generator (shared with timer/event
counter).

I/O
Pull-high*
Bidirectional I/O lines. Software instructions deter-
mine the CMOS output or SCHMITT trigger input
with a pull-high resistor (determined by pull-high op-
tions). The external interrupt and timer input are
pin-shared with the PC0 and PC1, respectively. The
external interrupt input is activated on a high to low
transition.

OSC1, OSC2 are connected to an RC network or Crys-
tal (determined by ROM code option) for the internal
system clock. In the case of RC operation, OSC2 is the
output terminal for 1/4 system clock. These two pins
also can be optioned as an RTC oscillator (32768Hz) or
I/O lines. In these two cases, the system clock comes
from an internal RC oscillator whose frequency has 4
options (3.2MHz, 1.6MHz, 800kHz, 400kHz). If the I/O
option is selected, the pull-high options also be en-
abled. Otherwise the PC3 and PC4 are used as inter-
nal registers (pull-high resistors always disabled).
* The pull-high resistors of each I/O port (PA, PB, PC) are controlled by an option bit.
