The FDC37B77x has four high-drive, open-drain
output, bidirectional port pins that can be used for
external serial interfaces, such as ISA external
keyboard and PS/2-type mouse interfaces. They are
KCLK, KDAT, MCLK, and MDAT. P26 is inverted and
output as KCLK. The KCLK pin is connected to
TEST0. P27 is inverted and output as KDAT. The
KDAT pin is connected to P10. P23 is inverted and
output as MCLK. The MCLK pin is connected to
TEST1. P22 is inverted and output as MDAT. The
MDAT pin is connected to P11. NOTE: External pull-
ups may be required.
KEYBOARD POWER MANAGEMENT
The keyboard provides support for two power-saving
modes: soft powerdown mode and hard powerdown
mode. In soft powerdown mode, the clock to the ALU
is stopped but the timer/counter and interrupts are still
active. In hard power down mode the clock to the
8042 is stopped.
Soft Power Down Mode
This mode is entered by executing a HALT
instruction. The execution of program code is halted
until either RESET is driven active or a data byte is
written to the DBBIN register by a master CPU. If
this mode is exited using the interrupt, and the IBF
interrupt is enabled, then program execution resumes
with a CALL to the interrupt routine, otherwise the
next instruction is executed. If it is exited using
RESET then a normal reset sequence is initiated and
program execution starts from program memory
location 0.
Hard Power Down Mode
This mode is entered by executing a STOP
instruction. The oscillator is stopped by disabling the
oscillator driver cell. When either RESET is
driven active or a data byte is written to the DBBIN
register by a master CPU, this mode will be exited (as
above). However, as the oscillator cell will require an
initialization time, either RESET must be held active
for sufficient time to allow the oscillator to stabilize.
Program execution will resume as above.
INTERRUPTS
The FDC37B77x provides the two 8042 interrupts.
IBF and the Timer/Counter Overflow.
MEMORY CONFIGURATIONS
The FDC37B77x provides 2K of on-chip ROM and
256 bytes of on-chip RAM.
Register Definitions
Host I/F Data Register
The Input Data register and Output Data register are
each 8 bits wide. A write to this 8 bit register will load
the Keyboard Data Read Buffer, set the OBF flag and
set the KIRQ output if enabled. A read of this register
will read the data from the Keyboard Data or
Command Write Buffer and clear the IBF flag. Refer
to the KIRQ and Status register descriptions for more
information.
Host I/F Status Register
The Status register is 8 bits wide. Table 50 shows
the contents of the Status register.
