3.3.3
The CPU can access a 16-Mbyte address space in advanced mode. The on-chip ROM is enabled.
Pins P13 to P10, and ports A, B and C function as input ports immediately after a reset. Address
(A23 to A8) output can be enabled or disabled by bits AE3 to AE0 in the pin function control
register (PFCR) regardless of the corresponding data direction register (DDR) values. Pins for
which address output is disabled among pins P13 to P10 and in ports A and B become port outputs
when the corresponding DDR bits are set to 1.
Port C is an input port immediately after a reset. Addresses A7 to A0 are output by setting the
corresponding DDR bits to 1.
Ports D and E function as a data bus, and part of port F carries data bus signals.
The initial bus mode after a reset is 8 bits, with 8-bit access to all areas. However, note that if 16-
bit access is designated by the bus controller for any area, the bus mode switches to 16 bits and
port E becomes a data bus.
3.3.4
The CPU can access a 16-Mbyte address space in advanced mode. The on-chip ROM is enabled,
but external addresses cannot be accessed.
All I/O ports are available for use as input-output ports.
Mode 6 (Supported Only by the H8S/2218 Group)
