Output pins High Current inverting output pins. May be used for
LED or backlight drivers. Their state is set up via OUT_PORT2.
Upon reset OUT_PORT 2[7:6] are reset low. Due to the inverting
nature of the outputs this means OUT 2[7] and OUT 2[6] are high.

6. EXTERNAL PORTS AND MULTIPLEXER
The ACE9050 contains 2 external ports, addition to the 6303
Port1 and Port2 which a described in section 1 ‘ACE9050 6303R
Description’. One of the ports is an input register (IN_PORT1),
the other an output (OUT_PORT2). Both are 8-bit, but not all bits
are accessible from outside the ACE9050.
Two bits from OUT_PORT2 are fed to a multiplexer. This
enables multiple functions to share the same external pin, thus
reducing the overall pin count. The functions multiplexed with the
port are the Pulse Width Modulators and the ACE serial Interface
Latch2. Selection is made via the ACE9050 control Port 5.
Further I/O capability can be obtained by using the Keypad
interface as standard ports. This is described in the ‘Keypad
Interface’ section of the data sheet.
External Pins
INPUTS
INRQ1, INRQ0:
External Port and Interrupt Input (pins 70 & 71)
The logic level of these external inputs are read via
IN_ PORT1[1:0], regardless of whether these inputs are
configured to generate interrupts or not.
INP1[4], INP1[3], INP1[2]:
External Port Inputs (pins 54,53,52)
Uncommitted input. The logic level of these pins can be read
via IN_PORT1[4:2].
SERV
: Service Input (pin 74)
The state of the mode select line SERV can be read by
software via IN_PORT1. The function of SERV is described in
‘Modes Of Operation’ section.
TXPOW:
Power Detect input (pin 61)
The TXPOW input goes to the Watchdog and ATO block,
refer to ‘Autonomous Timeout’ section for more details. The state
of the input can be read via IN_PORT1.
OUTPUTS
OUTP2 [0]/CPUCL
OUT_PORT2[0] or CPUCL Clock (pin 94)
When the CPUCL Clock Output is disabled in the Clock
Generator this pin is driven by the OUT_PORT2 [0]. Refer to
‘Clock Generator’ section for details of the CPUCL function.
OUTP2 [1]/PWM1
(pin 98)
This pin can be either be driven from OUT_PORT2[1] or the
Pulse Width Modulator 1. The selection is made via Port5[0].
OUTP2 [2]/PWM2/Latch2
(pin 81)
This pin can be driven from: OUT_PORT 2[2], Pulse Width
Modulator 2 or ACE Serial Interface Latch2. The selection is
made via Port 5[5:4].
