Function
Connected to a plus power supply.
Connected to a 0 V power supply.
I/O pins of the system clock generating circuit. Connect a ceramic resonator
between pins XIN and XOUT. The feedback resistor is built-in between pins XIN
and XOUT.
1-bit I/O port. For input use, set the latch of the specified bit to “0.” When the built-
in pull-down transistor is turned on, the key-on wakeup function using “H” level
sense and the pull-down transistor become valid. The output structure is P-channel
open-drain.
2-bit (E0, E1) output port. The output structure is P-channel open-drain.
3-bit input port. For input use (E0, E1), set the latch of the specified bit to “0.”
When the built-in pull-down transistor is turned on, the key-on wakeup function
using “H” level sense and the pull-down transistor become valid. Port E2 has an
input-only port and has a key-on wakeup function using “H” level sense and pull-
down transistor.
4-bit I/O port. For input use, set the latch of the specified bit to “0.” The output structure
is P-channel open-drain. When the built-in pull-down transistor is turned on, the key-
on wakeup function using “H” level sense and pull-down transistor become valid.
Carrier wave output pin for remote control. The output structure is CMOS circuit.
