REGISTER
Automotive, Two-Channel Proximity and
Data Pointer Control Register (16-Bit Register)
This register is set to 0004h on all forms of reset.
Unrestricted read/write.
Reserved. Read returns 0.
Word/Byte Select 0. This bit selects access mode for DP[0]. When WBS0 is set to logic 1, the DP[0] is
operated in word mode for data-memory access; when WBS0 is cleared to logic 0, DP[0] is operated in
byte mode for data-memory access.
Reserved. Read returns 0.
General Register (16-Bit Register)
This register is cleared to 0000h on all forms of reset.
Unrestricted read/write.
General Register Bits [15:0]. This register is intended primarily for supporting byte operation on 16-bit
data. GR can be used as a 16-bit general-purpose register and allows byte-readable and byte-writable
operations through the corresponding GRL and GRH register locations. It also supports byte-swap
operation when read through the GRS register location.
General Register Low Byte (8-Bit Location)
This register is cleared to 00h on all forms of reset.
Unrestricted read/write.
General Register Low Byte Bits [7:0]. This register location reflects the low byte of the GR register and
is intended primarily for supporting byte operation on 16-bit data. Any data written to this location stores
in the low byte of the GR register, and a read in this location returns the least significant data byte of the
GR register.
General Register Byte Swap (16-Bit Location)
This register is cleared to 0000h on all forms of reset.
Unrestricted read only.
General Register Byte Swap Bits [15:0]. This read-only register location reflects the byte-swapped
data of the GR register and is intended primarily for supporting byte operation on 16-bit data. Reading
this register location returns the byte-swapped data from the GR register.
General Register High Byte (8-Bit Location)
This register is cleared to 00h on all forms of reset.
Unrestricted read/write.
General Register High Byte Bits [7:0]. This register location reflects the high byte of the GR register
and is intended primarily for supporting byte operation on 16-bit data. Any data written to this location
stores in the high byte of the GR register, and read this location returns the most significant data byte
of the GR register.
General Register Sign Extended Low Byte (16-Bit Location)
This register is cleared to 0000h on all forms of reset.
Unrestricted read only.
General Register Sign Extended Byte Bits [15:0]. This read-only register location reflects the sign
extended low byte of the GR register. When read, the upper 8 bits contain the logic value of bit 7
of the GR register, and the lower 8 bits are the low byte of the GR register.
