Serial controller
The NS7520 supports two independent universal asynchronous/synchronous receiver/transmitter
channels. Each channel supports these features:
Independent programmable bit-rate generator
UART and SPI (master) modes
High-speed data transfer:
x1 mode: 4Mbits/sec
x16 mode: 230 Kbits/sec
32–byte TX FIFO
32–byte RX FIFO
Programmable data format: 5–8 data bits; odd, even, or no parity; 1, 2 stop bits
Programmable channel modes: normal, local loopback, remote loopback
Control signal support
Maskable interrupt conditions:
Receive break detection
Receive framing error
Receive parity error
Receive overrun error
Receive FIFO ready
Receive FIFO half-full
Transmit FIFO ready
Transmit FIFO half-empty
CTS, DSR, DCD, RI state change detection
Clock/data encoding: NRZ, NRZB, NRZI, FM, Manchester
Multi-drop capable
