Register Reference
Master Internal Time Register (TWIMITR)
The TWI control register (TWIMITR, shown in Figure A-57 and described
in Table A-54) is used to enable the TWI module as well as to establish a
relationship between the peripheral clock (PCLK) and the TWI controller’s
internally-timed events. The internal time reference is derived from PCLK
using the prescaled value:
PRESCALE = f
PCLK
/10 MHz
0x4488 RXTWI8 8-Bit FIFO Receive Register
0x448C RXTWI16 16-Bit FIFO Receive Register
