Notes 1. The WAKEUP pin is multiplexed with the INT4 pin. With the µPD77111 and 77112, the function of the WAKEUP pin can be

activated or deactivated by mask option. With the µPD77110, this function is always valid.

2. These pins are provided only on the µPD77110. The PLL0 and PLL1 pins are multiplexed with the P2 and P3 pins.
