Alternate Functions of
Port D
78
ATmega162/V
The Port D pins with alternate functions are shown in
Table 38. Port D Pins Alternate Functions
The alternate pin configuration is as follows:
• RD – Port D, Bit 7
RD is the external data memory read control strobe.
• WR – Port D, Bit 6
WR is the external data memory write control strobe.
• TOSC2/OC1A – Port D, Bit 5
TOSC2, Timer Oscillator pin 2: When the AS2 bit in ASSR is set (one) to enable asynchronous
clocking of Timer/Counter2, pin PD5 is disconnected from the port, and becomes the inverting
output of the Oscillator amplifier. In this mode, a crystal Oscillator is connected to this pin, and
the pin can not be used as an I/O pin.
OC1A, Output Compare Match A output: The PD5 pin can serve as an external output for the
Timer/Counter1 Output Compare A. The pin has to be configured as an output (DDD5 set (one))
to serve this function. The OC1A pin is also the output pin for the PWM mode timer function.
