An ‘*’ at the end of the signal name denotes active low.
Pin Name
Type
Description
BigEndian
Input
Allows the system to change the processor addressing mode without
rewriting the mode ROM.
VccOK
Input
Vcc is OK
When asserted, this signal indicates to the RM5261A that both power
supplies has been above the recommended value for more than 100
milliseconds and will remain stable. The assertion of VccOK initiates
the reading of the boot-time mode control serial stream.
ColdReset*
Input
Cold reset
This signal must be asserted for a power on reset or a cold reset.
ColdReset must be de-asserted synchronously with SysClock.
Reset*
Input
Reset
This signal must be asserted for any reset sequence. It may be
asserted synchronously or asynchronously for a cold reset, or
synchronously to initiate a warm reset. Reset must be de-asserted
synchronously with SysClock.
ModeClock
Output
Boot mode clock
Serial boot-mode data clock output at the system clock frequency
divided by 256.
ModeIn
Input
Boot mode data in
Serial boot-mode data input.
Pin Name
Type
Description
VccInt
Input
Power supply for core.
VccIO
Input
Power supply for I/O.
Vss
Input
Ground return.
