Pin Information
DS352PP3
JUL 2001
The selection between SSI2 and the codec is controlled by the state of the SERSEL bit in SYSCON2
(
Section 5.2.2 SYSCON2 System Control Register 2
). The choice between the SSI2, codec, and
the MCP is controlled by the MCPSEL bit in SYSCON3 (
Section
5.2.3 SYSCON3 System Control
Register 3
).
NOTE:
All deglitched inputs are via the 16.384 kHz clock. Therefore, the input signal must be active for at
least ~61
μ
s to be detected cleanly.
The following output pins are implemented as bi-directional pins to enable the output side of the pad
to be monitored and hence provide more accurate control of timing or duration:
RUN
The
RUN
pin is looped back in to skew the address and data bus from each other.
NCAS[3:0]
The
NCAS
pins are looped back into the EP7211 to be used as the actual clock
source for the data to be latched internally.
Drive 0
and
1
Drive 0
and
1
are looped back in on power up to determine what polarity the output
of the PWM should be when active.
DD[3:0]
DD[3:0]
are looped back in on power up to enable the reading of the ID of some
LCD modules.
