I/O PORTS
The 7630 group has 35 programmable I/O pins and one input pin
arranged in five I/O ports (ports P0 to P4). The I/O ports are con-
trolled by the corresponding port registers and port direction regis-
ters; each I/O pin can be controlled separately.
When data is read from a port configured as an output port, the port
latch’s contents are read instead of the port level. A port configured
as an input port becomes floating and its level can be read. Data
written to this port will affect the port latch only; the port remains
floating.
Refer to Structure of port- and port direction registers, Structure of
port I/Os (1) and Structure of port I/Os (2).

Structure of port- and port direction registers
Port Pij direction control bit (j = 0 to 7)
0 : Port configured as input
1 : Port configured as output
Note : The direction control bits corresponding to P10, P11, P35, P36 and
P37 are not used (“0” when read, do not write “1”). Port direction re-
gisters are undefined when read (write only).

Port Pi direction register (i = 0 to 4) (address 000916 + 2 i)
PiD
Port Pij control bit (j = 0 to 7)
0 : “L” level
1 : “H” level
Note :
The control bits corresponding to P10, P35, P36 and P37 are not used
(“0” when read, do not write “1”).
