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.
Input/Output ports are described in the following sections.
40-Pin PDIP #
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 signal is applied, a High output state can cause the CMOS input buffer to float.
This may 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
instruction, it will read the actual value at the input logic not from the output buffer.
In addition, the instruction of "OR", "AND", "XOR" are read-modify-write instructions.
It will first read the port and then modify the value and load back to the port.
Precaution must be taken if the port is configured as open-drain output or driving some
circuit that may make the voltage different from the desired output logic. For example,
pins P00-P07 are not connecting to anything else. If it is configured as open-drain out-
