FUNCTIONAL DESCRIPTION
CL-PS7110
Low-Power System-on-a-Chip
Figure 1-5. Video Buffer Mapping
The refresh rate is not affected by the number of bits per pixel. However, the LCD controller fetches twice
the data per refresh for 4-bits-per-pixel compared to 2-bits-per-pixel. The main reason for reducing the
number of bits per pixel is to reduce the power consumption of the DRAMs in bank 0 where the video
buffer is mapped.
1.2.11 Internal UART and SIR Encoder
The CL-PS7110 contains a built-in UART, which offers similar functionality to the National Semiconduc-
tor
16C550 device. It can support bit rates of up to 115.2 kbps and contains two 16-byte FIFOs for
receive and transmit.
Only three modem-control input signals are supported: CTS, DSR, and DCD. The additional RI input
modem control line is not supported. Output modem control lines (such as, RTS and DTR) are not explic-
itly supported, but can be implemented using bits from the general-purpose PIA ports in the CL-PS7110.
