;* NAME: PRGRNGE
;* PURPOSE:
;* Program a FLASH address range which is maximum 32 bytes in the
;* same row. Bus frequency must be between 1.0MHz and 8.4MHz.
;* ENTRY CONDITIONS:
;* H:X contains a start address of the FLASH address range
;* LADDR:LADDR+1 contains a last address of the FLASH address range
;* DATA array contains the data to be programmed to the FLASH
;* (maximum 32 bytes)
;* CPUSPD contains a nearest integer of 4 x bus frequency (MHz)
;* EXIT CONDITIONS:
;* H:X contains a next FLASH address; I-bit set
;* SUBROUTINES CALLED:
;* VARIABLES READ: CPUSPD, LADDR:LADDR+1, DATA array
;* VARIABLES MODIFIED: LADDR(ByteCntr):LADDR+1(RamPntrLo)
;* The values are modified, but they are restored with original
;* values before exiting from this routine.
;* STACK SIZE: 9 bytes (including the call to this routine)
;* SIZE: 132 bytes
;* DESCRIPTION: EXECUTED OUT OF ROM
;* This routine can program the FLASH only in the same row.
;* Therefore, the total programing byte No. is maximum 32 bytes.
;* The COP is serviced in this routine. The first COP is serviced on
;* 59 bus cycles after this routine is called in the user software.
;* However, there could still be a COP time out if the COP is not
;* serviced within a proper period in user software.
