2.3 Ravin-L Pin FunctionsFor Ravin-L only a single pinout is available. It is set up by the following registersetting:If SYSBOOTMODE.BOOTMODE9 = 0 (IRAM disabled): SYSPINMUX = 00ED 0003HPINMUX[3:0] = 0011B pinout option 3 (fixed)all SMUXm = 0 no SMUX selection (fixed)BUFPUEN[7:0] = EDHinternal pull-up resistors enabled for- group 7: HINT, HLBDRQ, HLBCS, MDFBCLK- group 6: n.c.- group 5: n.c.- group 3: n.c.- group 2: n.c.- group 0: n.c.If SYSBOOTMODE.BOOTMODE9 = 1 (IRAM enabled): SYSPINMUX = 00FD 0003HPINMUX[3:0] = 0011B pinout option 3 (fixed)all SMUXm = 0 no SMUX selection (fixed)BUFPUEN[7:0] = FDHinternal pull-up resistors enabled for- group 7: HINT, HLBDRQ, HLBCS, MDFBCLK- group 6: n.c.- group 5: n.c.- group 4: n.c.- group 3: n.c.- group 2: n.c.- group 0: n.c.Features The Ravin-L pinout provides following features:• 8-bit LBus Host-I/F- multiplexed address/data bus HLBD[7:0]• Video Output I/F 0- 18-bit RGB(6/6/6)- composite VO0CSYNC or separate VO0HSYNC/VO0VSYNC• 16-bit SDRAM/SRAM-I/FChapter 2 Pin Functions30 Preliminary User's Manual S19203EE1V3UM00
