User Manual

C Configuration

The configurable parameters for the I

C driver are located in the i2c_conf.c source file

that accompanies the RZK release in the following path:

<ZDSII installed directory>\Program Files\Zilog\

ZDSII_eZ80Acclaim!_A.B.C\ZTP\ZTPX.Y.Z_Lib\RZK\Conf

To change any of the I

C parameters, include this file in the project and set the appropriate

values, as defined in Table 8.

Flash Drivers

Flash drivers are implemented as simple APIs that do not operate within the constructs of

the DDF. To access these functions directly, include the device header files in the applica-

tion.

Table 8. Configurable I

C Drivers

Variable/Macro Default Value Description/Valid Values

I2C_TASK_STACK_SIZEH 1024 Stack size of the I

C interrupt thread.

I2C_RX_MAX_BUFF_SIZEH 100 Size of the Rx circular queue.

I2C_TASK_PRIORITYH 6 Priority of the I

C Interrupt thread.

i2cConfigParams {0xB0,

0x00,0x58,

I2C_MASTER,

RZK_FALSE,

0x00,2}

i2cConfigParams currSlaveAddr The slave address with which the master communi-

cates, for example, 0xA0.

i2cConfigParams selfAddr The address of eZ80 when acting as a slave.

i2cConfigParams speed The speed of the I

C bus, for example, 0x58.

i2cConfigParams mode I2C_MASTER/I2C_SLAVE;

determines whether eZ80 will act as a master or

slave.

i2cConfigParams useSubAddr RZK_TRUE/RZK_FALSE; determines whether to use

subaddresses for the slave device.

i2cConfigParams subAddr subaddress value for the slave; used only if the use-

SubAddr Flag is set to RZK_TRUE.

i2cConfigParams addrLen Length of subaddress; the number of subaddress

bytes sent to the slave are based on this value.
