The SRAM options are configured by two jumpers, JP8 and JP11, and resistors R62
and R63. Their locations on the board are shown in Figure 4-8.
FIGURE 4-8:
To configure for the 256 KByte address range (default):
1. Set JP11 (callout 2) to position 1-2 to connect PMA17 to LED D4 only, and use
2. If installed, remove resistor R63 (callout 2) (disconnects PMA18 signal).
3. For TFT displays using 8 bpp color depth, install jumper JP8 to enable Byte
To enable the 512 KByte range of external SRAM:
1. Set jumper JP11 (callout 1) to position 2-3 (connects PMA17 signal to the
2. If installed, remove resistor R63 (callout 3) to disconnect PMA18 signal to the
3. Install jumper JP8 (callout 2) to enable Byte access in the external RAM. Byte
To enable the full 1 MByte address range for the SRAM (assuming U6 is populated with
a 1 Mbyte device):
1. Set jumper JP11 (callout 1) to position 2-3 (connects PMA17 signal to the
2. Populate resistor R63 (callout 3) with a
3. If installed, remove resistor R62 (callout 3) (disconnects PICtail Plus connector
4. For TFT displays using 8 bpp color depth, install jumper JP8 (callout 2) to enable
that microcontroller pin to control the LED.
Alternatively, remove jumper JP11 (disconnects PMA17 signal entirely).
