Latest Updated:02/26/2007

Question:

Is there any method of for using software to distinguish between the M16C/62P and the M16C/62A?

Answer:

It is possible to distinguish between the M16C/62A and the M16C/62P by the initial value of bit 3 (internal reserved area expansion bit) of the PM1 register.
The initial value of this bit is "0" for M16C/62A, and "1" for M16C/62P. Please read and determine this bit after reset release.
