Technical Data

NOTE:
NOTE:
D– and D+ — USB Data Pins
PTE4/D– pin has two programmable pullup resistors. One is used for
PTE4 when the USB module is disabled and another is used for D–
when the USB module is enabled.
TCH1–TCH0 — Timer Channel I/O Bits
TCLK — Timer Clock Input
Data direction register E (DDRE) does not affect the data direction of
port E pins that are being used by the TIM. However, the DDRE bits
always determine whether reading port E returns the states of the
latches or the states of the pins.
PTE4 pin functions as an external interrupt when PTE4IE=1 in the
IRQ option control register (IOCR) and USBEN=0 in the USB address
register (USB disabled). (See
D– and D+ are the differential data lines used by the USB module.
(See
The USB module enable bit, USBEN, in the USB address register
(UADDR) controls the pin options for PTE4/D– and PTE3/D+. When
the USB module is enabled, PTE4/D– and PTE3/D+ function as USB
data pins D– and D+. When the USB module is disabled, PTE4/D–
and PTE3/D+ function as 10mA open-drain pins for PS/2 clock and
data use.
The Pullup enable bit, PULLEN, in the USB control register 3 (UCR3)
enables a 1.5kΩ pullup on D– pin when the USB module is enabled.
(See
The PTE2/TCH1–PTE1/TCH0 pins are the TIM input capture/output
compare pins. The edge/level select bits, ELSxB and ELSxA,
determine whether the PTE2/TCH1–PTE1/TCH0 pins are timer
channel I/O pins or general-purpose I/O pins. (See
Interface Module
The PTE0/TCLK pin is the external clock input for the TIM. The
prescaler select bits, PS[2:0], select PTE0/TCLK as the TIM clock
input. When not selected as the TIM clock, PTE0/TCLK is available
for general purpose I/O. (See
(TIM).)
