Standby power supply (IRAMSTBY) for data retention
1.3.1.8
General Purpose I/O Support (GPIO)
•
24 address signals and 32 data signals
can be used for general-purpose I/O in single-chip mode
•
16 GPIO in MIOS14
•
Many peripheral signals can be used as GPIO when not used as primary functions
•
5-V outputs with slew rate control
1.3.2
Nexus Debug Port (Class 3)
•
Compliant with Class 3 of the IEEE-ISTO 5001-1999
•
Program trace via branch trace messaging (BTM)
•
Data trace via data write messaging (DWM) and data read messaging (DRM)
•
Ownership trace via ownership trace messaging (OTM)
•
Run-time access to on-chip memory map and special-purpose registers (SPRs) via the READI
read/write access protocol
•
Watchpoint messaging via the auxiliary port
•
9 or 16 full-duplex auxiliary pin interface for medium and high visibility throughput
•
All features configurable and controllable via the auxiliary port
•
Supports the RCPU debug mode via the auxiliary port

1.3.3.1
Two Time Processor Units (TPU3)
•
True 5 V I/O
•
Two time processing units (TPU3) with 16 channels each
•
Each TPU3 is a micro-coded timer subsystem
•
8 Kbytes of dual port TPU RAM (DPTRAM) shared by two TPU3 modules for TPU micro-code
1.3.3.2
22-Channel Modular I/O System (MIOS14)
•
Six modulus counter sub-modules (MCSM)
•
10 double-action sub-modules (DASM)
