6. Hardware Options
6.1. Functional Description
Hardware Options are available in several areas to
adapt the IC function to the host system requirements:
– clock signal selection for most of the peripheral
– interrupt source selection for interrupt inputs 5, 6, 7,
– Special Out signal selection for some U and H ports
– Rx/Tx polarity selection for SPI and UART modules
– U Port Slow Mode selection
In ROM parts Hardware Options are not software-pro-
grammable.
The data in address locations 00FFA0H through
00FFC3H were used to define their respective, hard-
wired Hardware Options during mask production and
can only be altered by changing a production mask for
this IC.
For verification purposes it is recommended to have
an application code in ROM that runs with FLASH
parts as well - which is automatically the case if
FLASH parts have been used for software develop-
ment and tests before. This implies reading of loca-
tions 00FFA0h through 00FFC3h directly after reset, to
activate the Hardware Options’ settings in FLASH and
EMU parts as well.
