timers and their associated pins. The timer pins are combined with other functions on the
port pins of the LPC2917/19, see
runs from 0 to 3).
Table 14.
The timer modules are clocked by two different clocks; CLK_SYS_PESS and CLK_TMRx
(x = 0-3), see
power management. The frequency of all these clocks is identical as they are derived from
the same base clock BASE_CLK_TMR. The register interface towards the system bus is
clocked by CLK_SYS_PESS. The timer and prescale counters are clocked by
CLK_TMRx.
The LPC2917/19 contains two identical UARTs located at different peripheral base
addresses. The key features are:
The UART is commonly used to implement a serial interface such as RS232. The
LPC2917/19 contains two industry-standard 550 UARTs with 16-byte transmit and receive
FIFOs, but they can also be put into 450 mode without FIFOs.
The two UARTs in the LPC2917/19 have the following pins. The UART pins are combined
with other functions on the port pins of the LPC2917/19.
