3.3

Diversity of TMP91CW12A and TMP91CP27

TMP91CP27 is article cut function and pin from TMP91CW12A fundamentally.

Specification of function shows section 3.3.1 to 3.3.6. Wide difference of AC/DC characteristic

is AC characteristics (Shown section 3.3.7). For the details, please refer to Chapter 4, “Electrical

characteristics”.

3.3.1

Cut Internal I/O

TMP91CP27 is micro controller cut 8-bit timer (TMRA6 to TMRA7), 16-bit timer

(TMRB1) and clock doublers circuit (DFM) from TMP91CW12A.

Please don’t access to special function register address of above internal I/O in

TMP91CW12A.

Please refer to “Table of special function register”.

3.3.2

Cut Port Function

TMP91CP27 be cut below port function from TMP91CW12A.

• Port 2: P27 (A23/A7) and P26 (A22/A6)

• Port 3: P37, P36 (

), P35 ( BUSAK ), P34 ( BUSRQ ) and P33 ( WAIT )

• Port 4: P43 ( CS3 )

• Port 5: P57 to P54 (AN7 to AN4)

• Port 6: P66, P65 and P64 (SCOUT)

• Port 7: P75 (TA7OUT)

• Port 8: P87 (TB1OUT1), P86 (TB1OUT0), P85 (TB1IN1/INT8) and

P84 (TB1IN0/INT7)

• Port A: PA7 to PA4, PA3 to PA0 (INT4 to INT1)

3.3.3

Cut factor of Interrupt

TMP91CP27 be cut factor of interrupt by cut internal I/O and port function (Refer to

Table 3.5.1). Please don’t access to interrupt priority setting register for cut factor of

interrupt. Please refer to “table of special function register”.

3.3.4

Bus Release Function

TMP91CP27 don’t include bus release function by cutting bus request pin (P34) and bus

acknowledge pin (P35).

3.3.5

CS/WAIT Controller

When set TMP91CP27 to BxCS<BxW2:0>

= “010” (1 + N) WAIT mode, it operates as 1

wait by cutting WAIT pin.

And there is not CS3 pin (P43), but when set MSAR3, MAMR3 and set B3CS<B3E>

= “1”,

wait control is effective.
