Clock I/O for sending/receiving serial data.
Any of three type of internal clock and one external clock is
switched by program.
E
I
Analog data input.
Digital data input can be specified in a bit by program.
Upon resetting, analog input is specified.
G
O
LCD segment output or CMOS output can be switched in
4 ports by program.
Upon resetting, CMOS output is specified and polarity is "L".
F
