4. When Group A is Different in Mode from Group B
Group A and group B can be used by setting them in different modes each other at the same
time. When either group is set to mode 1 or mode 2, it is possible to set the one not defined
as a control pin in port C to both input and output as port which operates in mode 0 at the
3rd and 0th bits of the control word.
(Mode combinations that define no control bit at port C)
When the I/O bit is set to input in this case, it is possible to access data by the normal port
C read operation.
When set to output, PC7-PC4 bits can be accessed by the bit set/reset function only.
Meanwhile, 3 bits from PC2 to PC0 can be accessed by normal write operation.
The bit set/reset function can be used for all of PC3-PC0 bits. Note that the status of port C
varies according to the combination of modes like this.
