Table 11. System Signal Description
Signal
Name
Type
Description
Alternate
Function
AD[7:0]
I/O
Multiplexed Address/Data LSB for external access
Data LSB for Slave port access (used for 8-bit and 16-bit modes)
P0[7:0]
A[15:8]
I/O
Address Bus MSB for external access
Data MSB for Slave port access (used for 16-bit mode only)
P2[7:0]
RD
I/O
Read Signal
Read signal asserted during external data memory read operation.
Control input for slave port read access cycles.
P3.7
WR
I/O
Write Signal
Write signal asserted during external data memory write operation.
Control input for slave write access cycles.
P3.6
RST
I
Reset Input
Holding this pin low for 64 oscillator periods while the oscillator is running
resets the device. The Port pins are driven to their reset conditions when a
voltage lower than V
IL is applied, whether or not the oscillator is running.
This pin has an internal pull-up resistor which allows the device to be reset
by connecting a capacitor between this pin and VSS.
Asserting RST when the chip is in Idle mode or Power-down mode returns
the chip to normal operation.
This pin is set to 0 for at least 12 oscillator periods when an internal reset
occurs.
-
ALE
O
Address Latch Enable Output
The falling edge of ALE strobes the address into external latch. This signal
is active only when reading or writing external memory using MOVX
instructions.
-
PSEN
O
Program
Test mode entry signal. This pin must be set to VDD for normal operation.
-
EA
I
External Access Enable
This pin must be held low to force the device to fetch code from external
program memory starting at address 0000h. It is latched during reset and
cannot be dynamically changed during operation.

Alternate
Function
AVSS
GND
Alternate Ground
AVSS is used to supply the on-chip PLL and the USB PAD.
-
AVDD
PWR
Alternate Supply Voltage
AVDD is used to supply the on-chip PLL and the USB PAD.
-
VSS
GND
Digital Ground
VSS is used to supply the buffer ring and the digital core.
-
VDD
PWR
Digital Supply Voltage
VDD is used to supply the buffer ring on all versions of the device.
It is also used to power the on-chip voltage regulator of the Standard
versions or the digital core of the Low Power versions.
