6.5
The USB Controller is equipped with a free-running timer
driven by a clock one-sixth the resonator frequency. Bits 0
through 7 of the counter are readable from the read-only Timer
Register located at I/O address 0x23. The Timer Register is
cleared during a Power-On Reset and whenever Suspend
6.6
Interface with peripherals is conducted via as many as 16
GPIO signals. These signals are divided into two ports: Port 0
and Port 1. Port 0 contains eight lines (P0.0–P0.7) and Port 1
contains up to eight lines (P1.0–P1.7). The number of external
I/O pins depends on the package type. Both ports can be
accessed by the IORD, IOWR, and IOWX instructions. The

mode is entered. Figure 6-6 illustrates the format of this
register and Figure 6-7 is its block diagram.
With a 6 MHz resonator, the timer resolution is 1 s.
The timer generates two interrupts: the 128- s interrupt and
the 1.024-ms interrupt.
Port 0 data register is located at I/O address 0x00 while the
Port 1 data register is located at I/O address 0x01. The
contents of both registers are set HIGH during a reset. Refer
to Figures 6-8 and 6-9 for the formats of the data registers. In
addition to supporting general input/output functions, each I/O
line can trigger an interrupt to the microcontroller. Please refer
to the interrupt section for more details.
