LOAD — Pad Driver Load Bit
SHEN — Show Cycle Enable Bit
EMINT — Emulate Internal Address Space Bit
MODE[2:0] — Chip Configuration Mode Field
The LOAD bit selects full or default drive strength for selected pad
output drivers. For maximum capacitive load, set the LOAD bit to
select full drive strength. For reduced power consumption, clear the
LOAD bit to select default drive strength.
Table 4-2
The SHEN bit enables the external memory interface to drive the
external bus during internal transfer operations.
In emulation mode, the SHEN bit is read-only. In all other modes, it is
a read/write bit.
The EMINT bit enables chip select 1 (CS1) to decode the internal
memory address space.
The EMINT bit is read-always but can be written only in emulation
mode.
This read-only field reflects the chip configuration mode, as shown in
Table
