TTL
Chip Select.
When CS is HIGH, the microprocessor interface
port, D
7-0
, is set to HIGH impedance and ignored. When CS is
LOW, the microprocessor can read or write parameters over
D
7-0
. One additional falling edge of CS is needed to move input
data to its assigned working registers.
Bus Read/Write Control.
When R/W and CS are LOW, the
microprocessor can write to the control registers or CLUT over
D
7-0
. When R/W is HIGH and CS is LOW, it can read the
contents of any CLUT address or control register over D
7-0
.
Master Reset Input.
Bringing RESET LOW sets the software
reset control bit, SRESET, LOW, forcing the internal state
machines to their starting states and disabling all outputs.
Bringing RESET HIGH synchronizes the internal pixel clock
(PCK = PXCK / 2) to maintain a defined pipeline delay through
the TMC22x91. If HRESET is set HIGH, the encoder is enabled
when RESET goes HIGH. If HRESET is LOW, the host restarts
the TMC22x91 by setting SRESET HIGH. RESET does not
affect the CLUT or the control registers, except SRESET.
