Capacitive Touch IO (CAPTIO)
14.3 CapTouch Registers
The Capacitive Touch IO registers and their address offsets are listed in Table 14-1 . In a given device,
multiple Capacitive Touch IO registers might be available. The base address of each Capacitive Touch IO
module can be found in the device-specific data sheet.
NOTE: All registers have half-word or byte access. For a generic register ANYREG , the suffix "_L"
( ANYREG_L ) refers to the lower byte of the register (bits 0 through 7). The suffix "_H"
( ANYREG_H ) refers to the upper byte of the register (bits 8 through 15).

NOTE: This is a 16-bit module and must be accessed ONLY through byte (8 bit) or half-word (16 bit)
access. 32-bit read or write access to this module causes a bus error.
