programmable bank-switching wait states
The programmable bank-switching logic of the ’5409 is functionally equivalent to that of the ’548/’549 devices.
This feature automatically inserts one cycle when accesses cross memory-bank boundaries within program or
data memory space. A bank-switching wait state can also be automatically inserted when accesses cross the
data space boundary into program space.
The bank-switching control register (BSCR) defines the bank size for bank-switching wait-states. Figure 5
shows the BSCR and its bits are described in Table 4.

NAME

BNKCMP
1111
Bank compare. BNKCMP determines the external memory-bank size. BNKCMP is used to mask the four
MSBs of an address. For example, if BNKCMP = 1111b, the four MSBs (bits 12–15) are compared, resulting
in a bank size of 4K words. Bank sizes of 4K words to 64K words are allowed.
11
PS-DS
1
Program read – data read access. PS-DS inserts an extra cycle between consecutive accesses of program
read and data read or data read and program read.
PS-DS = 0
No extra cycles are inserted by this feature.
PS-DS = 1
One extra cycle is inserted between consecutive data and program reads.
10–3
Reserved
0
These bits are reserved and are unaffected by writes.
HPI bus holder. HBH controls the HPI bus holder feature. HBH is cleared to 0 at reset
.
8-bit Mode
HBH = 0
The bus holder is disabled for the HPI data bus (HD[7:0]).
HBH = 1
The bus holders are enabled on HD[7:0]. When not driven, the HPI data bus (HD[7:0]) is held
in the previous logic level.
HPI bus holder. HBH controls the HPI bus holder feature. HBH is cleared to 0 at reset
.
16-bit Mode
HBH = 0
The bus holder is disabled for the HPI address bus (HA[15:0]). The HPI GPIO pins (HD[7:0])
are held in the previous logic level.
HBH = 1
The bus holders are enabled on HA[15:0]. When not driven, the HPI address bus (A[15:0])
and HPI GPIO pins (HD[7:0]) are held in the previous logic level.
2
HBH
0
1
BH
0
Bus holder. BH controls the data bus holder feature. BH is cleared to 0 at reset.
BH = 0
The bus holder is disabled.
BH = 1
The bus holder is enabled. When not driven, the data bus (D[15:0]) is held in the previous
logic level.
0
EXIO
0
External bus interface off. The EXIO bit controls the external bus-off function.
EXIO = 0
The external bus interface functions as usual.
EXIO = 1
The address bus, data bus, and control signals become inactive after completing the current
bus cycle. Note that the DROM, MP/MC, and OVLY bits in the PMST and the HM bit of ST1
cannot be modified when the interface is disabled.
