2.6 PMU (Power Management Unit)
The PMU outputs signals necessary for controlling the power of the entire system, including the V
R
4101. It also
controls the PLL of the V
R
4100 CPU core and the internal clocks (PClock, TClock, and MasterOut) in the power-saving
mode.
2.7 DMAAU (Direct Memory Access Address Unit)
The DMAAU controls five types of DMA transfer addresses.
2.8 DCU (Direct Memory Access Control Unit)
The DCU controls arbitration of five types of DMA transfers.
2.9 CMU (Clock Mask Unit)
The CMU controls supply of the clock (TClock or MasterOut) from the V
R
4100 CPU core to the internal peripheral
units.
2.10 GIU (General Purpose I/O Unit)
The GIU controls 12 GPIO pins and the DCD pin. Note, however, that of the 12 GPIO pins, one is reserved for a
specific application at present.
2.11 AIU (Audio Interface Unit)
The AIU can be used to generate any frequency by using PWM and outputs audio signals to external devices. It also
supplies a buzzer sound.
2.12 KIU (Keyboard Interface Unit)
The KIU has eight scan lines and eight detection lines to detect input of 64 keys. It can also detect roll over of 2 or 3
keys.
2.13 PIU (Touch Panel Interface Unit)
The PIU controls detection of touching on a touch panel. The V
R
4101 supports two types of A/D converter interfaces:
TLC2543C and TLV1543C.
2.14 DebugSIU (Debug Serial Interface Unit)
The DebugSIU is a serial interface for debugging and supports a transfer rate of up to 115 kbps.
2.15 SIU (Serial Interface Unit)
The SIU is a serial interface conforming to the RS-232C Standards, and supports a transfer rate of up to 115 kbps. In
addition, a IrDA serial interface that supports a transfer rate of 115 kbps is also included, though this IrDA serial interface
is exclusively used with the RS-232C interface.
