Example :Clearing the internal RAM of the TMP88PH40MG (clear all RAM addresses to 0, except bank 0)
The TMP88PH40MG contains 16Kbytes program memory (OTP) located at addresses 04000H to 07EFFH
The TMP88PH40MG contains 512bytes +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
