Bank
This is a method of addressing Data Memory. Since midrange devices have 7-bits for direct
addressing, instructions can address up to 128 bytes (including special function registers). To
allow more data memory to be present on a device, data memory is partitioned into contiguous
banks of 128 bytes each. To select the desired bank, the bank selection bits (RP1:RP0) need to
be appropriately configured. Since there are presently 2 bank selection bits, 4 banks can be
implemented.
Baud
Generally how the communication speed of serial ports is described. Equivalent to bits per sec-
ond (bps).
BCD
See Binary Coded Decimal.
Binary Coded Decimal (BCD)
Each 4-bit nibble expresses a digit from 0-9. Usually two digits are packed to a byte giving a
range of 0 - 99.
BOR
See Brown-out Reset.
Brown-out
A condition where the supply voltage of the device temporarily falls below the specified minimum
operation point. This can occur when a load is switched on and causes the system/device voltage
to drop.
Brown-out Reset (BOR)
Circuitry which will force the device to the reset state if the (device) voltage falls below a specified
voltage level. Some devices have an internal BOR circuit, while other devices would require an
external circuit to be created.
Bus width
This is the number of bits of information that the bus carries. For the Data Memory, the bus width
is 8-bits. For the midrange devices the Program Memory bus width is 14-bits.
