1.5 Pin Description
Apply 0V to the Vss pin. Apply following voltage to the Vcc pin.
2.7 to 5.5 V (Normal), 3.0 to 5.5 V (T-ver.), 4.2 to 5.5 V (V-ver.)
Supplies power to the A/D converter. Connect the AV
CC pin to VCC and
the AVSS pin to VSS
___________
The microcomputer 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 X
IN 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
Outputs the clock having the same frequency as f1, f8, f32, or fC
______ ________
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
