serial channel 2 and I/Os for an 8-bit timer. Writing 1 in the corresponding bit of the
port 8 function register P8FC enables those functions. Resetting resets P8CR and
P8FC to 0 and sets all bits to input ports.

Port 80 to 85 are 6-bit general-purpose I/O ports. I/O can be set on a bit basis.
Resetting sets port 80 to 85 as input ports. All bits of the output latch register are set
Port 86 to 87 are 2-bit I/O ports. I/O can be set on a bit basis. When using as output
Resetting sets the output latch register and the control register value to 1, and sets
In addition to functioning as I/O ports, port 86 to 87 also function as low-frequency
In addition to functioning as I/O ports, port 80 and 83 also function as TXD1 output
These ports are also used as the programmable open-drain mode.
