Chapter 19. Signal Descriptions
19-25
Timer Module Signals
19.11 Timer Module Signals
This section describes timer module signals.
19.11.1 Timer Input 0 (TIN0)
The timer input (TIN0) can be programmed to cause events to occur in timer counter 1. It
can either clock the event counter or provide a trigger to the timer value capture logic.
19.11.2 Timer Output (TOUT0)/PB7
Timer mode: Timer output (TOUT0) is the output from timer 0.
Port B mode: This pin can also be configured as I/O pin PB7.
19.11.3 Timer Input 1 (TIN1)/PWM Mode Output 2
(PWM_OUT2)
Timer mode: Timer input 1 (TIN1) can be programmed as an input that causes events to
occur in timer counter 2. This can either clock the event counter or provide a trigger to the
timer value capture logic.
PWM mode: Pulse-width modulator 2 (PWM_OUT2) compare output.
19.11.4 Timer Output 1 (TOUT1)/PWM Mode Output 1
(PWM_OUT1)
Timer mode: Timer output (TOUT1) is the output from timer 1.
PWM mode: Pulse-width modulator 1 (PWM_OUT1) compare output.
19.12 Ethernet Module Signals
The following signals are used by the Ethernet module for data and clock signals.
These signals are multiplexed with the parallel port B PB15–PB8 signals.
19.12.1 Transmit Clock (E_TxCLK)
This is an input clock which provides a timing reference for E_TxEN, E_TxD[3:0] and
E_TxER.
19.12.2 Transmit Data (E_TxD0)
E_TxD0 is the serial output Ethernet data and is only valid during the assertion of Tx_EN.
This signal is used for 10-Mbps Ethernet data. This signal is also used for MII mode data
in conjunction with E_TxD[3:1].
