Zilog Developer Studio II – Z8 Encore!

User Manual

UARTS

In the

UARTs area, select the checkboxes for the UARTs that you are going to use.

The Z8 Encore! XP F1680 Series has a user-controlled

Program RAM (PRAM) area to

store interrupt service routines (ISRs) of high-frequency interrupts. Program RAM

ensures low average current and a quick response for high-frequency interrupts. To use

this feature, the ISRs in the ZSL UART must be provided with the option of being placed

in the PRAM segment. When you select the

Place ISR into PRAM checkbox, ZDS II

addresses the

zslF1680U0XXX.lib library, zslF1680U1XXX.lib library, or both

libraries to place ISRs for UART0 and UART1 in PRAM.

You can place ISRs in PRAM only when the UART is set in interrupt mode. To set the

UART in interrupt mode, edit the

include\zilog\uartcontrol.h header file by

defining the UART0_MODE/UART1_MODE symbol as MODE_INTERRUPT and

rebuilding the libraries. For more information about rebuilding the ZSL, see the Zilog

Standard Library API Reference Manual (RM0038).

For the Z8 Encore! XP F1680 Series, the default ZSL libraries are in the

zslF1680XXX.lib files.

The following functions are placed in PRAM segment within each library:

zslF1680U0XXX.lib

•

VOID isr_UART0_RX( VOID )

•

VOID isr_UART0_TX( VOID )

zslF1680U1XXX.lib

•

VOID isr_UART1_RX( VOID )

•

VOID isr_UART1_TX( VOID )
