Note 1: Setting this bit to "0" nullifies settings made to this register, so that the drive capability set by the Group 0,1 Output Drive

Capability Setting Register is assumed.

When this bit is set to "1," settings of the Group 0,1 Output Drive Capability Setting Register have no effect and the drive

capability is controlled by the P70DSEL bit.

Note 2: This bit selects the drive capability of the P70/CLKOUT/WR#/BCLK pin. For settings of this bit to take effect, the P70DSELEN

bit must be set to "1."

Note 3: The 50% drive capability is equivalent to that of the M32R/ECU series without the port output drive capability setting function.

Note : • For the pins other than the P70/CLKOUT/WR#/BCLK pin, the drive capability can be set by using the Port Group Output Drive

Capability Setting Registers. Note that 50% of GnDSEL and 50% of P70DSEL drive capabilities are equivalent.
