Monitor ROM (MON)
7.5.6 MON_LDRNGE
In monitor mode, LDRNGE is used to load the data array in RAM with data from a range of FLASH
locations.

The MON_LDRNGE routine is designed to be used in monitor mode. It performs the same function as the
LDRNGE routine (see 7.5.3 LDRNGE), except that MON_LDRNGE returns to the main program via an
SWI instruction. After a MON_LDRNGE call, the SWI instruction will return the control back to the monitor
code.
7.5.7 EE_WRITE
EE_WRITE is used to write a set of data from the data array to FLASH.

1. The minimum data size is 2 bytes. The maximum data size is 15 bytes.
2. The start address must be a page boundary start address: $xx00, $xx40, $xx80, or $00C0.
The start location of the FLASH to be programmed is specified by the address ADDRH:ADDRL and the
number of bytes in the data array is specified by DATASIZE. The minimum number of bytes that can be
