Keyboard

V Reset

This parameter is set to 2.6V.

Watchdog Enable

This parameter should be set to Enable, but may be set to Disable for debug purposes.

4.3.2.2 SPI Master User Module

The SPI Master User Module is used to communicate with the radio transceiver. The radio trans-

ceiver supports leading edge data latching, non-inverted clock, and MSB first transmission as

defaults. A clock divisor of 6 is chosen which generates an SPI clock of 2 MHz. The interrupt API to

this module is not used. In the PRoC RDK keyboard design, the 4-wire mode is employed.

4.3.2.3 Programmable Interval Timer User Module

The Programmable Interval Timer User Module is configured to use the Internal 32-KHz Low-power

Oscillator. This module is used to provide a periodic interrupt to the timer code module in order to

maintain a power saving millisecond sleep routine. The period of the timer is calibrated to the system

clock at power on in order to provide a period of about 1 ms. This calibration is performed to account

for variations in temperature and ILO variances from part to part. Configure the module to generate a

terminal count interrupt. The period parameter is ignored since it is programmed at run time based

upon the calibration results. See the timer code module for more details on calibration.

4.3.2.4 Flash Security

The keyboard project within PSoC Designer has a file called FlashSecurity.txt. This file specifies

access rules to blocks of Flash ROM. See the documentation at the top of the file for definitions. This

file is shipped with a single change from its default configuration. The blocks starting at address

1FC0 hex are changed from W: Full (Write protected) to U: Unprotected. These locations of Flash

are dedicated to save non-volatile configuration values for the protocol code module and non-volatile

session key for the encrypt code module. Note when building the mouse firmware, be sure to check

that the text image size does not occupy this block.
