GnDSEL (Note 1)

0: 50%

Group n output drive capability select bit

4–6

No function assigned. Fix to "0."

(12–14)

7 (15)

GnDSEL (Note 1)

0: 50%

Group n output drive capability select bit

1: 100%

Note 1:The 50% drive capability is equivalent to that of the M32R/ECU series without the port output drive capability setting

function.

Note : • For the P70/CLKOUT/WR#/BCLK pin, the drive capability can be set to one of four capability levels by using the P70 Output

Drive Capability Setting Register. Note that 50% of GnDSEL bit and 50% of P70DSEL bit drive capabilities are equivalent.
