LPC11Cx2/Cx4
32-bit ARM Cortex-M0 microcontroller
7.11.2.6
Time-out function
A ‘TXD dominant time-out’ timer is started when the CAN_TXD signal of the C_CAN
controller is set LOW. If the LOW state on the CAN_TXD signal persists for longer than
t
to(dom)TXD
, the transmitter is disabled, releasing the bus lines to recessive state. This
function prevents a hardware and/or software application failure from driving the bus lines
to a permanent dominant state (blocking all network communications). The TXD dominant
time-out timer is reset when the CAN_TXD signal is set HIGH. The TXD dominant
time-out time also defines the minimum possible bit rate of 40 kbit/s.
7.12 10-bit ADC
The LPC11Cx2/Cx4 contains one ADC. The ADC is a single 10-bit successive
approximation ADC with eight channels.
7.12.1
Features
10-bit successive approximation ADC.
Input multiplexing among 8 pins.
Power-down mode.
Measurement range 0 V to V
DD
.
10-bit conversion time
2.44
s (up to 400 kSamples/s).
Burst conversion mode for single or multiple inputs.
Optional conversion on transition of input pin or timer match signal.
Individual result registers for each ADC channel to reduce interrupt overhead.
7.13 General purpose external event counter/timers
The LPC11Cx2/Cx4 includes two 32-bit counter/timers and two 16-bit counter/timers. The
counter/timer is designed to count cycles of the system derived clock. It can optionally
generate interrupts or perform other actions at specified timer values, based on four
match registers. Each counter/timer also includes one capture input to trap the timer value
when an input signal transitions, optionally generating an interrupt.
7.13.1
Features
A 32-bit/16-bit timer/counter with a programmable 32-bit/16-bit prescaler.
Counter or timer operation.
One capture channel per timer, that can take a snapshot of the timer value when an
input signal transitions. A capture event may also generate an interrupt.
Four match registers per timer that allow:
–
Continuous operation with optional interrupt generation on match.
–
Stop timer on match with optional interrupt generation.
–
Reset timer on match with optional interrupt generation.
Up to four external outputs corresponding to match registers, with the following
capabilities:
–
Set LOW on match.
–
Set HIGH on match.
