1.6 Pin Description
Apply 0V to the Vss pin. Apply following voltage to the Vcc pin.
2.7 to 5.5 V (M16C/26A, M16C/26B), 3.0 to 5.5 V (M16C/26T T-ver.), 4.2
to 5.5 V (M16C/26T V-ver.)
Supplies power to the A/D converter. Connect the AVCC 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 X
IN and XOUT. To apply external clock, apply
it to XIN 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
_______ _______
NMI interrupt input pin. 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
I/O pins for the timer A0 to A4
Input pins for the timer A0 to A4
Input pin for Z-phase
Timer B0 to B1 input pins
Output pins for the three-phase motor control timer
I/O pins for the three-phase motor control timer
Input pins to control data transmission
Output pins to control data reception
Inputs and outputs the transfer clock
Inputs serial data
Outputs serial data
Output pin for transfer clock
Applies reference voltage to the A/D converter
Analog input pins for the A/D converter
Input pin for an external A/D trigger
I/O ports for CMOS. Each port can be programmed for input or output
under the control of the direction register. An input port can be set, by
program, for a pull-up resistor available or for no pull-up resister available
in 3-bit units
CMOS I/O ports which have a direction register determines an individual
pin used as an input port or an output port. A pull-up resistor is selectable
for every 4 input ports
