Note.
Write to the oscillation circuit control
register 1 as the flow shown in Figure 2.
Oscillation circuit control register 1
Main clock division selection bit
0 : Main clock is divided by 2.
1 : Main clock is not divided by 2.
Main clock external input selection bit
0 : Main-clock oscillation circuit is operating by itself.
Watchdog timer is used at returning from STP state.
1 : Main-clock is input externally.
Watchdog timer is not used at returning from STP state.
Sub clock external input selection bit
0 : Sub-clock oscillation circuit is operating by itself.
P7
functions as X
pin.
Watchdog timer is used at returning from STP state.
1 : Sub-clock is input externally.
P7
functions as I/O port.
Watchdog timer is not used at returning from STP state.
Always “1” (“1” at reset)
0 : Always “0” (However, writing data “55
16
” shown in Figure 2 is possible.)

Note.
“Y” is the sum of bits to be set. For example,
when
setting bits 2 and 1 to “1”, “Y” becomes “6”.

BASIC FUNCTION BLOCKS
The M37733EHLXXXHP has the same functions as the
M37733MHBXXXFP except for the following :
(1)The built-in ROM is PROM.
(2)The package is different.
(3)The reset circuit is different.
(4)The status of bit 3 of the oscillation circuit control register 1 (address
6F
16
) at a reset is different.
(5)The usage condition of bit 3 of the oscillation circuit control register
1 is different.
Accordingly, refer to the basic function blocks description in the
M37733MHBXXXFP except for Figure 1 (bit configuration of the
oscillation circuit control register 1) , Figure 3 and Figure 4 (reset
circuit).
In the M37733EHLXXXHP, bit 3 of the oscillation circuit control
register 1 must be “1”. (Refer to Figure 1.) The status of this bit at
a reset is “1”.
