Bits PB[7:0] are associated with addresses ADDR[7:0] and DATA[7:0]
(except in narrow mode) respectively. When this port is not used for
external addresses such as in single-chip mode, these pins can be
used as general-purpose I/O. DDRB determines the primary direction
of each pin. This register is not in the on-chip map in expanded and
peripheral modes. Read and write anytime.
This register determines the primary direction for each port B pin
when functioning as a general-purpose I/O port. DDRB is not in the
on-chip map in expanded and peripheral modes. Read and write
anytime.
This register is associated with external bus control signals and
interrupt inputs, including data bus enable (DBE), mode select
(MODB/IPIPE1, MODA/IPIPE0), E clock, size (LSTRB), read/write
