Table 5. Description of Pin Function (2/4)
Type
Pin
Name
Input/Output
Function
Bus Control
CS0#, CS1#
Chip select
Output
Chip select signals for external devices.
RD#
Read
Output
This signal is output when reading external devices.
WR#
Write
Output
This signal is output when writing external devices.
BHW#
Byte High Write
Output
When writing to an external device, this signal indicates the valid byte
BLW#
Byte Low Write
Output
position to which data is transferred. BHW# and BLW# correspond to
the upper address side (bits 0-7 are valid) and the lower address side
(bits 8-15 are valid), respectively.
BHE#
Byte High Enable Output
During an external device access, this signal indicates that the high-
order data (bits 0-7) is valid.
BLE#
Byte Low Enable
Output
During an external device access, this signal indicates that the low-
order data (bits 8-15) is valid.
WAIT#
Wait
Input
If WAIT# input is low when the M32R accesses external devices, the
wait cycle extended.
HREQ#
Hold request
Input
This pin is used by an external device to request control of the external
bus. The M32R goes to a hold state when HREQ# input is pulled low.
HACK#
Hold acknowledge Output
This signal indicates to the external device that the M32R has entered
a hold state and relinquished control of the external bus.
Multijunction
TIN0, TIN3
Timer input
Input
Input pin for multijunction timer .
timer
TIN16-TIN23
TO0
Timer output
Output
Output pin for multijunction timer.
-TO20
TCLK0
Timer clock
Input
Clock input pin for multijunction timer.
-TCLK3
A-D
AVCC0
Analog power
-
AVCC0 is the power supply for the A-D0 converters. Connect AVCC0
converter
upply
to the power supply (5V or 3.3V).
AVSS0
Analog ground
-
AVSS0 is the analog ground for the A-D0 converters. Connect to
AVSS0 ground.
AD0IN0
Analog input
Input
16-channel analog input pin for A-D0 converter.
-AD0IN15
VREF0
Reference
Input
VREF0 is the reference voltage input pin (5V or 3.3V) for the A-D0
voltage input
converters.
Interrupt
SBI#
System break
Input
