162 / 234 page ![]() CC2430 CC2430 PRELIMINARY Data Sheet (rev. 1.03) SWRS036A Page 162 of 232 13.14.6 Flash Controller Registers The Flash Controller registers are described in this section. FCTL (0xAE) – Flash Control Bit Name Reset R/W Description 7 BUSY 0 R Indicates that write or erase is in operation 6 SWBSY 0 R Indicates that single write is busy; avoid writing to FWDATA register while this is true 5 - 0 R/W Not used. 4 CONTRD 0 R/W Continuous read enable mode 0 Avoid wasting power; turn on read enables to flash only when needed 1 Enable continuous read enables to flash when read is to be done. Reduces internal switching of read enables, but greatly increases power consumption. 3:2 0 R/W Not used. 1 WRITE 0 R0/W Page Write. Start writing page given by FADDRH:FADDRL. If ERASE is set to 1, a page erase is performed before the write. 0 ERASE 0 R0/W Page Erase. Erase page that is given by FADDRH[6:1] FWDATA (0xAF) – Flash Write Data Bit Name Reset R/W Description 7:0 FWDATA[7:0] 0x00 R/W Flash write data. Data written to FWDATA is written to flash when FCTL.WRITE is set to 1. FADDRH (0xAD) – Flash Address High Byte Bit Name Reset R/W Description 7 - 0 R/W Not used 6:0 FADDRH[6:0] 0x00 R/W High byte of flash address Bits 6:1 will select page to access, while bit 0 is MSB of row access. FADDRL (0xAC) – Flash Address Low Byte Bit Name Reset R/W Description 7:0 FADDRL[7:0] 0x00 R/W Low byte of flash address Bit 0 of FADDRH and bits 7:6 will select which row to write to, while bits 5:0 will select which location to write to. |
