Low-Power System-on-a-Chip
3.2.17 INTMR — Interrupt Mask Register
The Interrupt Mask register is a 16-bit read/write register used to selectively enable any of the 16 interrupt
sources within the CL-PS7110. The four shaded (see following table) interrupts all generate a fast inter-
rupt request to the ARM710A microprocessor; this causes a jump to processor virtual address
0000.0001C. All other interrupts generate a standard interrupt request; this causes a jump to processor
virtual address 0000.00018. See
Table 1-1 on page 14
for the interrupt allocation. Setting the appropriate
bit in this register enables the corresponding interrupt. All bits are cleared by a system reset.
3.2.18 LCDCON — LCD Control Register
The LCD Control register is a 32-bit read/write that controls the size of the LCD screen and the operating
mode of the LCD controller operates in. Refer to
Section 1.2.10
for more information on video buffer map-
ping and the LCD controller.
Video buffer size
The video buffer size field is a 13-bit field that sets the total number of bits
×
128 (quad
words) in the video display buffer. This is calculated from the formula:
Video buffer size = (Total bits in video buffer / 128)
1
For example, for a 640
×
240 LCD and 4 bits per pixel the size of the video buffer =
640
×
240
×
4 = 614400 bits
Video buffer size field = (614400 / 128)
1 = 4799 or 0x12BF h.
Line length
The line length field is a 6-bit field that sets the number of pixels in one complete line.
This field is calculated from the formula:
Line length = (No. pixels in line / 16)
1
For example, for 640
×
240 LCD Line length = (640 / 16)
1 = 39 or 0x27 h.
