AT89LP216
13. I/O Ports
The AT89LP216 can be configured for between 11 and 14 I/O pins. The exact number of I/O
pins available depends on the clock and reset options as shown in Table 13-1. All port pins are
5V tolerant as inputs, that is they can be pulled up or driven to 5.5V even when operating at a
lower V
CC such as 3V. Inputs use CMOS levels while outputs use TTL levels. An external pul-
lup is required to convert outputs to CMOS levels.
13.1
Port Configuration
All port pins on the AT89LP216 may be configured to one of four modes: quasi-bidirectional
(standard 8051 port outputs), push-pull output, open-drain output, or input-only. Port modes may
be assigned in software on a pin-by-pin basis as shown in Table 13-2. The Tristate-Port User
Fuse determines the default state of the port pins. When the fuse is enabled, all port pins default
to input-only mode after reset, with the exception of P1.4 which starts in quasi-bidirectional
mode. When the fuse is disabled, all port pins, with the exception of P1.0 and P1.1, default to
quasi-bidirectional mode after reset and are weakly pulled high. Each port pin also has a
Schmitt-triggered input for improved input noise rejection. During Power-down all the Schmitt-
triggered inputs are disabled with the exception of P1.3, P3.2 and P3.3, which may be used to
wake up the device. Therefore P1.3, P3.2 and P3.3 should not be left floating during Power-
down.
