1.6 Pin Description
Table 1.10 Pin Description (64-Pin, 80-Pin and 85-Pin Packages)
Apply 2.7 to 5.5V to the Vcc pin. Apply 0V to the Vss pin.
Supplies power to the A/D converter. Connect the AV
CC pin to VCC and
the AVSS pin to VSS.
___________
The MCU is in a reset state when "L" is applied to the RESET pin
Connect the CNVSS pin to VSS.
I/O pins for the main clock oscillation circuit. Connect a ceramic resonator
or crystal oscillator between XIN and XOUT. To apply external clock, apply
it to X
IN and leave XOUT open. If XIN is not used (for external oscillator or
external clock) connect XIN pin to VCC and leave XOUT open.
I/O pins for the sub clock oscillation circuit. Connect a crystal oscillator
between XCIN and XCOUT.
______ ________
Input pins for the INT interrupt. INT2 can be used for Timer A Z-phase
function.
_______ _______
Input pin for the NMI interrupt. NMI cannot be used as I/O port while the three-
_______
phase motor control is enabled. Apply a stable "H" to NMI after setting it's
direction register to "0" when the three-phase motor control is enabled.
Input pins for the key input interrupt
