8.4 Macro Service
The
m
PD784046 has a total of five types of macro service. Each macro service is outlined below.
(1) Counter mode: EVTCNT
Operation
(a) Increments or decrements an 8-bit macro service counter (MSC).
(b) A vectored interrupt request is generated when the value of MSC reaches 0.
MSC
+1 / _1
Application example:
Event counter, measurement of number of times of capture
(2) Block transfer mode: BLKTRS
Operation
(a) Transfers block data between the buffer and an SFR specified by the SFR pointer (SFRP).
(b) The transfer source and destination can be an SFR or buffer. The length of the data to be
transferred can be byte or word.
(c) The number of times data is to be transferred (block size) is specified by MSC.
(d) MSC is auto-decremented (–1) each time the macro service has been executed.
(e) When the value of MSC has reached 0, a vectored interrupt request is generated.
Application example:
Data transfer/reception of serial interface
MSC
SFRP
_1
Buffer N
Buffer 1
SFR
Internal bus
