Timer n Register [R/W]
■ Timer 0 Register 0xC010
■ Timer 1 Register 0xC012
Register Description
The Timer n Register sets the Timer n count. Both Timer 0 and
Timer 1 decrement by one every 1 µs clock tick. Each can
provide an interrupt to the CPU when the timer reaches zero.
Count (Bits [15:0])
The Count field sets the Timer count.
General USB Registers
There is one set of registers dedicated to general USB control.
This set consists of two identical registers: one for Host/Device
Port 1 and one for Host/Device Port 2. This register set has
functions for both USB host and USB peripheral options and is
covered in this section and summarized in Table 43. USB Host
only registers are covered in UART Interface on page 7, and USB
device only registers are covered in External Memory Registers
on page 23.
USB n Control Register [R/W]
■ USB 1 Control Register 0xC08A
■ USB 2 Control Register 0xC0AA
Register Description
The USB n Control register is used in both host and device mode.
It monitors and controls the SIE and the data lines of the USB
ports. This register can be accessed by the HPI interface.
Port B D+ Status (Bit 15)
The Port B D+ Status bit is a read only bit that indicates the value
of DATA+ on Port B.
1: D+ is HIGH
0: D+ is LOW
