Table 5. 40- and 48-Pin Configuration (Continued)
This pin connects a parallel-resonant crystal or ceramic resonator to the on-chip oscillator
input. Additionally, an optional external single-phase clock can be coded to the on-chip
oscillator input.
This pin connects a parallel-resonant crystal or ceramic resonant to the on-chip oscillator
output.
40-Pin PDIP No
The CMOS input buffer for each Port 0, 1, or 2 pin is always connected to the pin, even
when the pin is configured as an output. If the pin is configured as an open-drain output
and no external signal is applied, a High output state can cause the CMOS input buffer
to float. This might lead to excessive leakage current of more than 100 µA. To prevent
this leakage, connect the pin to an external signal with a defined logic level or ensure
its output state is Low, especially during STOP mode.
Internal pull-ups are disabled on any given pin or group of port pins when programmed
into output mode.
Port 0, 1, and 2 have both input and output capability. The input logic is always present
no matter whether the port is configured as input or output. When doing a READ in-
struction, the MCU reads the actual value at the input logic but not from the output buff-
er. In addition, the instructions of OR, AND, and XOR have the Read-Modify-Write
sequence. The MCU first reads the port, and then modifies the value and load back to
the port.
Precaution must be taken if the port is configured as open-drain output or if the port is
driving any circuit that makes the voltage different from the desired output logic. For
example, pins P00–P07 are not connected to anything else. If it is configured as
