MIR3: Power Down Length Count [15:8] (PDLC)
This register is used to determine the length of power
down cycles. Before execution of the power down se-
quence, the 80188 core must load the PDLC counter.

MIR4: Power Down Length Count [22:16] (PDLC)
This register is used to determine the length of power
down cycles. Before execution of the power down se-
quence, the 80188 core must load the PDLC counter.

MIR5: Free Count [7:0] (FCNT)
This register is a read-only register. Do not write to this
register or unexpected consequences will result.
This register gives the value of the lowest byte of the free
running count. The free running count is a 24-bit counter

MIR6: Free Count [15:8] (FCNT)
This register gives the value of the lowest byte of the free
running count. The free running count is a 24-bit counter
that uses the 32 kHz clock as its basis. The free running

Description
Middle 8 bits of the length of the power down counter. The resolu-
tion of the power down length counter is in increments of PMX1/2
periods. The nominal PMX1/2 crystal value is 32.768 kHz, resulting
in a resolution of 31.25 s.
Description
When set to a 1, this bit prevents the normal termination of the
power down sequence, such that the PDLC and PUCT counts are
ignored, and the power down mode is only exited when the
PCMCIA PWRDWN bit is written with a 0, or when the SIR0
DISPWDN bit is written with a 1.
Upper 7 bits of the length of the power down counter. The resolution
of the power down length counter is in increments of PMX1/2 peri-
ods. The nominal PMX1/2 crystal value is 32.768 kHz, resulting in a
resolution of 31.25 s.

Upon execution of the power down sequence, the PDLC
value will be counted down to zero and the power down
cycle will end.
