Function
External Access Enable
When held at high level, instructions are fetched from the
internal program memory when the PC is less than 4000 H
(C505(C)(A)-2R) or 8000
4E/C505CA-4E). When held at low level, the C505 fetches
all instructions from external program memory.
For the C505 romless versions (i.e. C505-L, C505C-L,
C505A-L and C505CA-L) this pin must be tied low.
For the ROM protection version EA pin is latched during
reset.
Port 0
is an 8-bit open-drain bidirectional I/O port. Port 0 pins that
have 1’s written to them float, and in that state can be used
as high-impendance inputs. Port 0 is also the multiplexed
low-order address and data bus during accesses to external
program or data memory. In this application it uses strong
internal pullup transistors when issuing 1’s.
Port 0 also outputs the code bytes during program
verification in the C505 ROM versions. External pullup
resistors are required during program verification.
Reference voltage for the A/D converter.
Reference ground for the A/D converter.
