VDD
3.3V Supply voltage.
GND
Ground.
Port 1
Port 1 is an 8-bit bi-directional I/O port with internal pull-ups. The Port 1 output buffers can sink/source four TTL
inputs. When port 1 pins are written as 1’s, these pins are pulled high by the internal pull-ups and can be used as inputs. As
inputs, Port 1 pins that are externally being pulled low will source current (I
IL
) because of the internal pull-ups. Port 1 also
receives the low-order address bytes during OTP programming and verification.
P1.0 serves as functions of Buzz used driving buzzer, because this pin design for more driving capability than other
general I/O.
Port 3
Port 3 is an 8-bit bi-directional I/O port with internal pull-ups. The Port 3 output buffers can sink/source four TTL
inputs. When port 0 pins are written as 1’s, these pins are pulled high by the internal pullups and can be used as inputs. As
inputs, Port 3 pins that are externally being pulled low will source current (I
IL
) because of the pullups.
Port 3 also serves the functions of various special features of the T81L0001A as listed below:
Alternate Function:
P3.0:
RXD
P3.1:
TXD
P3.2:
INT0
P3.3:
INT1
P3.4:
T0
RST
Reset input and active high. When high on this pin should be lasting for two machine cycles while the oscillator is
running resets the device.
XIN
Input to the inverting oscillator amplifier and input to the internal clock operating circuit in BK,BD parts.
XOUT
Output from the inverting oscillator amplifier in BK,BD part.
