P89LPC9331/9341/9351/9361
8-bit microcontroller with accelerated two-clock 80C51 core
Since N ranges from 0 to 15, the CCLK frequency can be in the range of PCLK to
PCLK/16.
7.22.9 CCU interrupts
There are seven interrupt sources on the CCU which share a common interrupt vector.
7.23 UART
The P89LPC9331/9341/9351/9361 has an enhanced UART that is compatible with the
conventional 80C51 UART except that Timer 2 overflow cannot be used as a baud rate
source. The P89LPC9331/9341/9351/9361 does include an independent baud rate
generator. The baud rate can be selected from the oscillator (divided by a constant),
Timer 1 overflow, or the independent baud rate generator. In addition to the baud rate
generation, enhancements over the standard 80C51 UART include Framing Error
detection, automatic address recognition, selectable double buffering and several
interrupt options. The UART can be operated in four modes: shift register, 8-bit UART,
9-bit UART, and CPU clock/32 or CPU clock/16.
7.23.1 Mode 0
Serial data enters and exits through RXD. TXD outputs the shift clock. 8 bits are
transmitted or received, LSB first. The baud rate is fixed at 116 of the CPU clock
frequency.
