TMS470PLF111

16/32-BIT RISC FLASH MICROCONTROLLER

SPNS113 – OCTOBER 2006

POST OFFICE BOX 1443

• HOUSTON, TEXAS 77251-1443

device identification code register

The device identification code register identifies the coprocessor status, an assigned device-specific part num-

ber, the technology family (TF), the I/O voltage, whether or not parity is supported, the levels of flash and RAM

erro detection, and the device version. The PLF111 device identification code register value is 0x0006_3405.
