Data Memory (RAM)
The TMP88FW45AFG contains 120Kbytes program memory (Flash) located at addresses 04000H to
The TMP88FW45AFG contains 4Kbytes +128bytes RAM. The first 128bytes location (00040H to 000BFH)
The content of the data memory is indeterminate at power-on, so be sure to initialize it in the initialize rou-
Note:Because general-purpose registers exist in the RAM, never clear the current bank address of RAM. In
the above example, the RAM is cleared except bank 0.
