P1.0 - P1.7. General purpose I/O Port 1.
34
RST - Active high reset input. A logic 1 applied to this pin will activate a reset state. This
pin is pulled down internally so this pin can be left unconnected if not used.
36
P3.0 RXD. General purpose I/O port pin 3.0. Also serves as the receive signal for the on
board UART. This pin should not be connected directly to a PC COM port.
38
P3.1 TXD. General purpose I/O port pin 3.1. Also serves as the transmit signal for the on
board UART. This pin should not be connected directly to a PC COM port.
39
P3.2 INT0 . General purpose I/O port pin 3.2. Also serves as the active low External
Interrupt 0.
40
P3.3 INT1 . General purpose I/O port pin 3.3. Also serves as the active low External
Interrupt 1.
41
P3.4 T0. General purpose I/O port pin 3.4. Also serves as the Timer 0 input.
44
P3.5 T1. General purpose I/O port pin 3.5. Also serves as the Timer 1 input.
45
P3.6 WR . General purpose I/O port pin. Also serves as the write strobe for Expanded bus
operation.
46
P3.7 RD . General purpose I/O port pin. Also serves as the read strobe for Expanded bus
operation.
47, 48
XTAL2, XTAL1. Used to connect an external crystal to the internal oscillator. XTAL1 is
the input to an inverting amplifier and XTAL2 is the output.
52, 53
GND. Logic ground.
49, 50, 51,
56, 58, 60,
64, 66
P2.0-P2.7. General purpose I/O Port 2. Also serves as the MSB of the Expanded Address
bus.
68
PSEN
- Program Store Enable. This active low signal is used to enable an external
program memory when using the Expanded bus. It is normally an output and should be
unconnected if not used. PSEN is also used to invoke the Bootstrap Loader. At this time,
PSEN
will be pulled down externally. This should only be done once the DS5000FP is
already in a reset state. The device that pulls down should be open drain since it must not
interfere with PSEN under normal operation.
70
ALE - Address Latch Enable. Used to de-multiplex the multiplexed Expanded
Address/Data bus on Port 0. This pin is normally connected to the clock input on a ’373
type transparent latch. When using a parallel programmer, this pin also assumes the
PROG
function for programming pulses.
73
EA
- External Access. This pin forces the DS5000FP to behave like an 8031. No internal
memory (or clock) will be available when this pin is at a logic low. Since this pin is pulled
down internally, it should be connected to +5V to use NV RAM. In a parallel
programmer, this pin also serves as VPP for super voltage pulses.
