Нашел еще ошибку в IAR - в просмотрщике регистров SSC нет регистров SSC_RC0R и SSC_RC1R, а также нет многих полей в регистрах SSC.
Разобрался, как исправить эту ошибку. Нужно отредактировать текстовый файл ioat91sam7x256.ddf. В IAR версии 4.41A он находится в папке %ProgramFiles% \ IAR Systems \ Embedded Workbench 4.0 Evaluation \ ARM \ config. В IAR версии 5 он находится в папке %ProgramFiles% \ IAR Systems \ Embedded Workbench 5.0 Evaluation \ ARM \ config \ debugger \ Atmel. Это определения всех регистров, которые можно видеть в IDE IAR в режиме отладки.
[Регистры SSC_RC0R и SSC_RC1R]
Я внес следующие изменения в файл DDF:
1. Поправил группу регистров SSC (добавил регистры SSC_RC0R и SSC_RC1R). Было:
group = "SSC", "SSC_CR", "SSC_CMR", "SSC_RCMR", "SSC_RFMR", "SSC_TCMR", "SSC_TFMR", "SSC_RHR", "SSC_THR", "SSC_RSHR", "SSC_TSHR", "SSC_SR", "SSC_IER", "SSC_IDR", "SSC_IMR"
Стало:
group = "SSC", "SSC_CR", "SSC_CMR", "SSC_RCMR", "SSC_RFMR", "SSC_TCMR", "SSC_TFMR", "SSC_RHR", "SSC_THR", "SSC_RSHR", "SSC_TSHR", "SSC_RC0R", "SSC_RC1R", "SSC_SR", "SSC_IER", "SSC_IDR", "SSC_IMR"
2. Добавил описание регистров SSC_RC0R и SSC_RC1R в секции "========== Register definition for SSC peripheral ==========":
sfr = "SSC_RC0R", "Memory", 0xfffd4038, 4, base=16
sfr = "SSC_RC1R", "Memory", 0xfffd403C, 4, base=16
3. Добавил определение поля CKG в регистры SSC_RCMR и SSC_TCMR в секции "========== Register definition for SSC peripheral ==========":
sfr = "SSC_RCMR.CKG", "Memory", 0xfffd4010, 4, base=16, bitRange=6-7
sfr = "SSC_TCMR.CKG", "Memory", 0xfffd4018, 4, base=16, bitRange=6-7
4. Добавил определение поля STOP в регистр SSC_RCMR в секции "========== Register definition for SSC peripheral ==========":
sfr = "SSC_RCMR.STOP", "Memory", 0xfffd4010, 4, base=16, bitRange=12
5. Добавил определение полей CP0 и CP1 в регистр SSC_SR в секции "========== Register definition for SSC peripheral ==========":
sfr = "SSC_SR.CP0", "Memory", 0xfffd4040, 4, base=16, bitRange=8
sfr = "SSC_SR.CP1", "Memory", 0xfffd4040, 4, base=16, bitRange=9
6. Добавил определение полей CP0 и CP1 в регистр SSC_IMR в секции "========== Register definition for SSC peripheral ==========":
sfr = "SSC_IMR.CP0", "Memory", 0xfffd404c, 4, base=16, bitRange=8
sfr = "SSC_IMR.CP1", "Memory", 0xfffd404c, 4, base=16, bitRange=9

[Регистры SPI_CSR]
Изменения, которые я добавил в файл ioat91sam7x256.ddf IAR 4.41A, чтобы корректно отображались регистры SPI0_CSR0, SPI0_CSR1, SPI0_CSR2, SPI0_CSR3 и SPI1_CSR0, SPI1_CSR1, SPI1_CSR2, SPI1_CSR3.
