NOTES :
1. The CS0 pin outputs a low signal, and the CS1 to CS3 pins output a bank number.
2. If PM13 bit in the PM1 register is set to â0â, 15 Kbytes of the internal RAM and 192 Kbytes of the internal ROM can be used.
3. For flash memory version, when the PM10 bit in the PM1 register is set to â1â, 0F000h to 0FFFFh can be used as internal ROM area.
