Table 1. Pin Descriptions (Sheet 2 of 2)
Name
Description
P5.5/BHE#/WRH#
Byte High Enable or Write High output, as selected by the CCR. BHE# = 0 selects the
bank of memory that is connected to the high byte of the data bus. A0 = 0 selects the
bank of memory that is connected to the low byte. Thus accesses to a 16-bit wide
memory can be to the low byte only (A0 = 0, BHE# = 1), to the high byte only (A0 = 1,
BHE# = 0) or both bytes (A0 = 0, BHE# = 0). If the WRH# function is selected, the pin
goes low if the bus cycle is writing to an odd memory location. BHE#/WRH# is only valid
during 16-bit external memory write cycle. Also an LSIO pin when not BHE#/WRH#.
P5.6/READY
P5.4/SLPINT
P6.2/T1CLK
P6.3/T1DIR
PORT 1/EPA0–7
P6.0–6.1/EPA8–9
PORT 0/ACH0–7
P6.3-6.7/SSIO
PORT 2
PORT3 and 4
Ready input to lengthen external memory cycles, for interfacing with slow or dynamic
memory, or for bus sharing. If the pin is high, CPU operation continues in a normal
manner. If the pin is low prior to the falling edge of CLKOUT, the memory controller goes
into a wait state mode until the next positive transition in CLKOUT occurs with READY
high. When external memory is not used, READY has no effect. The max number of wait
states inserted into the bus cycle is controlled by the CCR/CCR1. Also an LSIO pin when
READY is not selected.
Dual-function I/O pin. As a bidirectional port pin or as a system function. The system
function is a Slave Port Interrupt Output Pin.
Dual-function I/O pin. Primary function is that of a bidirectional I/O pin, however, it may
also be used as a TIMER1 Clock input. The TIMER1 increments or decrements on both
positive and negative edges of this pin.
Dual-function I/O pin. Primary function is that of a bidirectional I/O pin, however, it may
also be used as a TIMER1 Direction input. The TIMER1 increments when this pin is high
and decrements when this pin is low.
Dual-function I/O port pins. Primary function is that of bidirectional I/O. System function is
that of High Speed capture and compare. EPA0 and EPA2 have another function of
T2CLK and T2DIR of the TIMER2 timer/counter.
8-bit high-impedance input-only port. These pins can be used as digital inputs and/or as
analog inputs to the on-chip A/D converter. These pins are also used as inputs to
EPROM parts to select the Programming Mode.
Dual-function I/O ports that have a system function as Synchronous Serial I/O. Two pins
are clocks and two pins are data, providing full duplex capability.
8-bit multi-functional port. All of its pins are shared with other functions.
8-bit bidirectional I/O ports with open drain outputs. These pins are shared with the
multiplexed address/data bus which has strong internal pullups.
