3.1.11 CHI Interface Signals
Table 3.1.11 CHI Interface Signals
Signal Name Type Description Initial State
CHIFS Input/output
PU
CHI Frame synchronization
CHI frame synchronization signal. This pin can be used in either output or input mode.
In output mode, the pin allows the TX4925 to become the master CHI synchronization
source. In input mode, the pin allows the external peripheral device to become the
master CHI synchronization source. In that case, the TX4925 CHI module becomes a
slave for external synchronization.
The pin is shared with other functions (refer to Section "3.3 Pin Multiplexing").
PIO input
CHICLK Input/output
PU
CHI Clock
CHI clock signal. This pin can be used in either output or input mode. In output mode,
the pin allows the TX4925 to become the master CHI clock source. In input mode, the
pin allows the external peripheral device to become the master CHI clock source. In
that case, the TX4925 CHI module becomes a slave for the external clock.
The pin is shared with other functions (refer to Section "3.3 Pin Multiplexing").
PIO input
CHIDOUT Output
PU
CHI Data Output
CHI serial data output signal.
The pin is shared with other functions (refer to Section "3.3 Pin Multiplexing").
PIO input
CHIDIN Input
PU
CHI Data Input
CHI serial data input signal.
