REFERENCE INFORMATION
LBP16
SPACE 0: HOSTMOT2 REGISTERS
Example: read first 5 entries in hostmot2 IDROM:
85420004
85
; 85 == NN = 5 | Inc bit (0x80) so address is incremented after each
access
42
; Read from space 0 with address included after command
00
; LSB of address (IDROM starts at 0x0400)
04
; MSB of address (IDROM starts at 0x0400)
Example: write 4 GPIO ports starting at 0x1000:
84C20010AAAAAAAABBBBBBBBCCCCCCCCDDDDDDDD
84
; 84 == NN = 4 | Inc bit so address is incremented after each access
C2
; Write to space 0 with address included after command
00
; LSB of address (GPIO starts at 0x1000)
10
; MSB of address (GPIO starts at 0x1000)
AAAAAAAA
; 32 bit data for GPIO port 0 at 0x1000
BBBBBBBB
; 32 bit data for GPIO port 0 at 0x1004
CCCCCCCC
; 32 bit data for GPIO port 0 at 0x1008
DDDDDDDD
; 32 bit data for GPIO port 0 at 0x100C
Note like all LBP16 data, write data is LS byte first
