Terminal Functions
The 5409 Terminal Functions table lists each pin name, function, and operating mode(s) for the 5409 device.
Some of the 5409 pins can be configured for one of two functions; a primary function and a secondary function.
The names of these pins in secondary mode are shaded in grey in Table 22.

O/Z
Parallel address bus A22 [most significant bit (MSB)] through A0 [least significant bit (LSB)]. The
lower sixteen address pins (A15 to A0) are multiplexed to address all external memory (program,
data) or I/O while the upper seven address pins (A22 to A16) are only used to address external
program space. These pins are placed in the high-impedance state when the hold mode is enabled,
or when OFF is low.

I/O/Z
Parallel data bus D15 (MSB) through D0 (LSB). The sixteen data pins (D15 to D0) are multiplexed
to transfer data between the core CPU and external data/program memory or I/O devices. The data
bus is placed in the high-impedance state when not outputting or when RS or HOLD is asserted.
The data bus also goes into the high-impedance state when OFF is low.
The data bus has bus holders to reduce the static power dissipation caused by floating, unused
pins. These bus holders also eliminate the need for external bias resistors on unused pins. When
the data bus is not being driven by the 5409, the bus holders keep the pins at the previous logic level.
The data bus holders on the 5409 are disabled at reset and can be enabled/disabled via the BH bit
of the bank-switching control register (BSCR).
I = Input, O = Output, Z = High-impedance, S = Supply
Although this pin includes an internal pulldown resistor, a 470- external pulldown is required. If the TRST pin is connected to multiple DSPs,
a buffer is recommended to ensure the VIL and VIH specifications are met.
