9.4 OPERATION IN A/D CONVERSION MODE
The timing necessary for A/D conversion differs depending on whether the main clock or subclock is selected as
the system clock.
(1) When main clock is selected as system clock
The following wait times must be set in software in the A/D conversion mode.
Wait time <1>: Time of transition from operation stop mode to A/D conversion mode (8 instruction cycles)
Wait time <2>: Wait time until value can be set to ADCR (3 instruction cycles)
Wait time <3>: Wait time until compare result register can be read (4 instruction cycles)
Sets A/D conversion mode
(VREFEN, ADCEN, ADCCH1, ADCCH0)
Wait time < 1 > + wait time < 2 >
(11 instruction cycles)
Sets ADCR (80H)
Reads ADCCMP
(Set + compare)
Wait time < 3 > (4 instruction cycles)
Wait time < 2 > (3 instruction cycles)
Wait time < 3 > (4 instruction cycles)
Wait time < 2 > (3 instruction cycles)
(Set + compare)
Sets ADCR (40H or 0C0H)
Reads ADCCMP
An example of a program for A/D conversion when the main clock is selected is shown below.
