3.2.3 Single-Chip Mode
In single-chip mode (BERR = 0), pins DATA[15:0] are configured as two 8-bit I/O ports. ADDR[18:3] are
configured as two 8-bit I/O ports. There is no external data bus path. Expanded mode configuration op-
tions are not available: I/O ports A, B, C, E, F, G, and H are always selected. BERR can be tied low
permanently to select single-chip mode.
3.3 Emulation Support
The SCIM contains logic that can be used to replace on-chip ports externally. It also contains special
support logic to allow external emulation of internal ROM. This emulation support allows system devel-
opment of a single-chip application in expanded mode.
Emulator mode is a special type of 16-bit expanded operation. It is entered by holding DATA10 low,
BERR high, and DATA1 low during reset. In emulator mode, all port A, B, E, G, and H data and data
direction registers and the port E pin assignment register are mapped externally. Port C data, port F
data and data direction registers, and port F pin assignment register are accessible normally in emulator
mode.
An emulator chip select (CSE) is asserted whenever any of the externally-mapped registers are ad-
dressed. The signal is asserted on the falling edge of AS. The SCIM does not respond to these access-
es, allowing external logic, such as a port replacement unit (PRU) to respond. Accesses to externally-
mapped registers require three clock cycles.
