NOTES :
1. ROM size depends on microcomputer type.
2. RAM size depends on microcomputer type.
3. To use a UART2, set the CRD bit in the U2C0 register to “1” (CTS/RTS function disabled).
4. There is no external connections for port P1, P4_4 to P4_7, P7_2 to P7_5 and P9_1 in 80-pin version.
Set the direction bits in these ports to “1” (output mode), and set the output data to “0” (“L”) using the program.
