RUNTIME CONTROL REGISTER DEFINITION
There are up to 256 addresses decoded inside the
DSM device for control and status information. 27
of these locations contain registers that the DSP
can access at runtime. The base address of this
block of 256 locations is referred to in this manual
as csiop(Chip Select I/O Port). Table 4 lists the 27
registers and their offsets (in hexadecimal) from
the csiopbase address needed to access individ-
ual DSM control and status registers. The DSP will
access these registers in I/O memory space using
its
IOMS
strobe. These registers are accesses in
bytes, so the DSP should ignore the upper byte of
its 16-bit I/O access.
Note1: All csiopregisters are cleared to logic 0 at
reset.
Note2: Do not write to unused locations within the
csiopblock of 256 registers. They should remain
logic zero.

Description
Data In
01
10
11
MCUI/O input mode. Read to obtain current logic level of
Port pins. No writes.
Data Out
05
12
13
MCU I/O output mode. Write to set logic level on Port
pins. Read to check status.
Direction
07
14
15
MCU I/O mode. Configures Port pin as input or output.
Write to set direction of Port pins.
Logic 1 = out, Logic 0 = in. Read to check status.
Drive Select
09
16
17
Write to configure Port pins as either standard CMOS or
Open Drain on some pins, while selecting high slew rate
on other pins. Read to check status.
Input Macrocells
0B
18
Read to obtain state of IMCs. No writes.
Enable Out
0D
1A
1B
Read to obtain the status of the output enable logic on
each I/O Port driver. No writes.
Output Macrocells AB
20
Read to get logic state of output of OMC bank AB.
Write to load registers of OMC bank AB.
Output Macrocells BC
21
Read to get logic state of output of OMC bank BC.
Write to load registers of OMC bank BC.
Mask Macrocells AB
22
Write to set mask for loading OMCs in bank AB. A logic
1 in a bit position will block reads/writes of the
corresponding OMC. A logic 0 will pass OMC value.
Read to check status.
Mask Macrocells BC
23
Write to set mask for loading OMCs in bank BC. A logic
1 in a bit position will block reads/writes of the
corresponding OMC. A logic 0 will pass OMC value.
Read to check status.
Main Flash Sector
Protection
C0
Read to determine Main Flash Sector Protection
Setting. No writes.
Security Bit and
Secondary Flash
Sector Protection
C2
Read to determine if DSM devices Security Bit is active.
Logic 1 = device secured.
Also read to determine Secondary Flash Protection
Setting status. No Writes.
JTAG Enable
C7
Write to enable JTAG Pins (optional feature). Read to
check status.
PMMR0
B0
Power Management Register 0. Write and read.
PMMR2
B4
Power Management Register 2. Write and read.
Page
E0
Memory Page Register. Write and read.
