Internal Peripherals
The following internal peripherals are available on the CPC1600 module:
2.2.1
Flash Memory
There are three flash devices available - one is used for the BIOS storage, one is a 32 MB NAND
flash solid-state disk, and one is a CompactFlash card in the socket.
2.2.1.1
CompactFlash
CPC1600 has a standard Compact Flash type I/II socket, which can accept CompactFlash memory
card for use as a disk drive connected to IDE channel. The CompactFlash socket is located on the
bottom side of the board. Please, refer to a subsection “
” below in this
Chapter for details on this connector and its pinout.
2.2.1.2
Solid-State Disk
A 32 MB onboard solid state disk may be used for operating system storage.
2.2.1.3
BIOS Flash
CPC1600 has 2 MB flash memory for BIOS storage.
2.2.2
Timers
CPC1600 is equipped with the following timers:
¢
RTC – Real-Time Clock
The ICH contains a MC146818A-compatible real-time clock. The RTC includes 256 bytes of
battery-backed CMOS RAM. RTC features include timekeeping with alarm function and 100-year
calendar, as well as programmable periodic interrupt. A coin-cell battery powers the real-time clock
and CMOS memory.
¢
Counter/Timer
Three 8254-type counters/timers are available on the CPC1600.
¢
Additional Timer
The ICH includes an additional programmable timer, which prevents system hang-ups during start-
ups. After the first time-out period is over, it generates the SMI# signal, which starts the software
hang-up recovery subroutine. If the second timeout ends, the "Reset" signal is issued to recover
the system from the hardware hang-up state.
