FXTH87E
FXTH87E, Family of Tire Pressure Monitor Sensors
Z = Zero indicator, bit 1
C = Carry/borrow, bit 0 (carry out of bit 7)
10.6.6 CCR activity notation
– = Bit not affected
0 = Bit forced to 0
1 = Bit forced to 1
Þ = Bit set or cleared according to results of operation
U = Undefined after the operation
10.6.7 Machine coding notation
dd = Low-order 8 bits of a direct address 0x0000–0x00FF (high byte assumed to be 0x00)
ee = Upper 8 bits of 16-bit offset
ff = Lower 8 bits of 16-bit offset or 8-bit offset
ii = One byte of immediate data
jj = High-order byte of a 16-bit immediate data value
kk = Low-order byte of a 16-bit immediate data value
hh = High-order byte of 16-bit extended address
ll = Low-order byte of 16-bit extended address
rr = Relative offset
10.6.8 Source form
Everything in the source forms columns, except expressions in italic characters, is literal
information that must appear in the assembly source file exactly as shown. The initial
3- to 5-letter mnemonic is always a literal expression. All commas, pound signs (#),
parentheses, and plus signs (+) are literal characters.
n — Any label or expression that evaluates to a single integer in the range 0–7
opr8i — Any label or expression that evaluates to an 8-bit immediate value
opr16i — Any label or expression that evaluates to a 16-bit immediate value
opr8a — Any label or expression that evaluates to an 8-bit value. The instruction treats
this 8-bit value as the low order 8 bits of an address in the direct page of the 64-Kbyte
address space (0x00xx).
opr16a — Any label or expression that evaluates to a 16-bit value. The instruction treats
this value as an address in the 64-Kbyte address space.
oprx8 — Any label or expression that evaluates to an unsigned 8-bit value, used for
indexed addressing
oprx16 — Any label or expression that evaluates to a 16-bit value. Because the HCS08
has a 16-bit address bus, this can be either a signed or an unsigned value.
rel — Any label or expression that refers to an address that is within –128 to +127
locations from the next address after the last byte of object code for the current
FXTH87ERM
