Description
About the M16C/62M (80-pin version) group (low voltage version)
The M16C/62M (80-pin version) group (low voltage version) is packaged in a 80-pin plastic mold pack-
age. The number of pins in comparison with the 100-pin package products is decreased. So be careful
about the following.
(a) The M16C/62M (80-pin version) group (low voltage version) supports single chip mode alone. It
(b) The input/output ports given below are absent from the M16C/62M (80-pin version) group (low
(c) INT3 to INT5 allocated to P1
(d) The output pins of timers A1 and A2 - TA1
(e) The UART2 input/output pins - CLK2 and CTS/RTS - allocated to P7
(f) The input pin TB1
(g) The input pin S
(h) The output pins for three-phase motor control allocated to P7
supports neither memory expansion mode nor microprocessor mode.
voltage version). To stabilize the internal state, set to output mode the direction register of each
input/output port. Failing in setting to output mode involves an increase in current consumption.
