Port B (PB7..0)
Port B is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The
Port B output buffers have symmetrical drive characteristic with both high sink and source cur-
rent capability. As inputs, Port B pins that are externally pulled low will source current if the
pull-up resistors are activated. The Port B pins are tri-stated when a reset condition becomes
active, even if the clock is not running.
Port B also serves the functions of various special features of the ATA6289 as listed on Section
2.4.4
Port C (PC2..0)
Port C is a 3-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The
Port C output buffers have symmetrical drive characteristic with both high sink and source cur-
rent capability. As inputs, Port C pins that are externally pulled low will source current if the
pull-up resistors are activated. The Port C pins are tri-stated when a reset condition becomes
active, even if the clock is not running.
Port C also serves the functions of various special features of the ATA6289 as listed on Section
2.4.5
Port D (PD7..0)
Port D is a 8(4)-bit bi-directional I/O port with internal pull-up resistors (selected for each bit).
The PD(6..3) pins are used as internal inter-die connections I/O ports. The Port D output buffers
have symmetrical drive characteristic with both high sink and source current capability. As
inputs, Port D pins that are externally pulled low will source current if the pull-up resistors are
activated. The Port D pins are tri-stated when a reset condition becomes active, even if the clock
is not running.
Port D also serves the functions of various special features of the ATA6289 as listed on Section
2.4.6
RESET
Reset input. A low level on this pin for longer than the minimum pulse length will generate a
reset, even if the clock is not running. The minimum pulse length is given in Table 3-13 on page
42. Shorter pulses are not guaranteed to generate a reset.
2.4.7
LF (2..1)
Input coil pins for the LF-Receiver.
