PRELIMINARY—SUBJECT TO CHANGE WITHOUT NOTICE

GND

BVS1

O,X

Buffered PCMCIA slot A Voltage Sense 1. In fact IP_A0. Used in

conjunction with BVS2 to determine the operation voltage of a

PCMCIA card. In case of MPC823 or MPC850 daughter boards,

connected to IP_B0 signal of the MPC.

GND

BRDY

O, H

Buffered PCMCIA slot A Ready signal. In fact IP_A7. Used as

PCMCIA port A Card Ready indication. In case of MPC823 or

MPC850 daughter boards, connected to IP_B7 signal of the

MPC.

GND

100

101

102

DP3

I/O, X

DP3/IRQ6~. Data Parity line 3 or Interrupt Request 6. May

generate and receive parity data for D(24:31) bits connected to

the DRAM SIMM. May also be conﬁgured as IRQ6~ input for the

MPC.

103

GND

104

BVS2

O, X

Buffered PCMCIA slot A Voltage Sense 2. In fact IP_A1. Used in

conjunction with BVS1 to determine the operation voltage of a

PCMCIA card. In case of MPC823 or MPC850 daughter boards,

connected to IP_B1 signal of the MPC.

105

GND

106

BCD1~

O, L

Buffered PCMCIA slot A Card Detect 1. In fact IP_A4. Input Port 4

of PCMCIA slot A. Used as Card Detect indication in conjunction

with BCD2~. In case of MPC823 or MPC850 daughter boards,

connected to IP_B4 signal of the MPC.

107

108

MODIN

O, X

This signal selects between clock generator and the 32768 Hz

crystal as clock sources for the MPC. Its is driven by DS2/4. See

2•3•2 “Clock Source Selection “on page 7. In the

motherboard documentations.

BBVD1

O, X

Buffered PCMCIA slot A Battery Voltage Detect 1. In fact IP_A6.

Used in conjunction with BBVD2 to determine the battery status

of a PC-Card. In case of MPC823 or MPC850 daughter boards,

connected to IP_B6 signal of the MPC.

111

GND

112

BCD2~

O, L

Buffered PCMCIA slot A Card Detect 2. In fact IP_A3. Input Port 3

of PCMCIA slot A. Used as Card Detect indication in conjunction

with BCD1~. In case of MPC823 or MPC850 daughter boards,

connected to IP_B3 signal of the MPC.
